An efficient synthesis of 1-aryl­isochromeno[3,4-d][1,2,3]triazol-5(1H)-ones, involving the diazo­tization of 3-amino-4-aryl­amino-1H-isochromen-1-ones in weakly acidic solution, has been developed and the spectroscopic characterization and crystal structures of four examples are reported. The mol­ecules of 1-phenyl­isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C15H9N3O2, (I), are linked into sheets by a combination of C—H⋯N and C—H⋯O hydrogen bonds, while the structures of 1-(2-methyl­phen­yl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C16H11N3O2, (II), and 1-(3-chloro­phen­yl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, C15H8ClN3O2, (III), each contain just one hydrogen bond which links the mol­ecules into simple chains, which are further linked into sheets by π-stacking inter­actions in (II) but not in (III). In the structure of 1-(4-chloro­phen­yl)isochromeno[3,4-d][1,2,3]triazol-5(1H)-one, (IV), isomeric with (III), a combination of C—H⋯O and C—H⋯π(arene) hydrogen bonds links the mol­ecules into sheets. When com­pound (II) was exposed to a strong acid in methanol, qu­anti­tative conversion occurred to give the ring-opened transesterification product methyl 2-[4-hy­droxy-1-(2-methyl­phen­yl)-1H-1,2,3-triazol-5-yl]benzoate, C17H15N3O3, (V), where the mol­ecules are linked by paired O—H⋯O hydrogen bonds to form centrosymmetric dimers.

An operationally simple and time-efficient approach has been developed for the synthesis of racemic N-substituted 3-(2-aryl-2-oxoeth­yl)-3-hy­droxy­indolin-2-ones by a piperidine-catalysed aldol reaction between aryl methyl ketones and N-alkyl­isatins. These aldol products were used successfully as strategic inter­mediates for the preparation of N-substituted (E)-3-(2-hetaryl-2-oxo­ethyl­idene)indolin-2-ones by a stereoselective dehydration reaction under acidic conditions. The products have all been fully characterized by 1H and 13C NMR spectroscopy, by mass spectrometry and, for a representative selection, by crystal structure analysis. In each of (RS)-1-benzyl-3-hy­droxy-3-[2-(4-meth­oxy­phen­yl)-2-oxoeth­yl]indolin-2-one, C24H21NO4, (Ic), and (RS)-1-benzyl-3-{2-[4-(di­methyl­amino)­phen­yl]-2-oxoeth­yl}-3-hy­droxy­indolin-2-one, C25H24N2O3, (Id), inversion-related pairs of mol­ecules are linked by O—H⋯O hydrogen bonds to form R22(10) rings, which are further linked into chains of rings by a combination of C—H⋯O and C—H⋯π(arene) hydrogen bonds in (Ic) and by C—H⋯π(arene) hydrogen bonds in (Id). The mol­ecules of (RS)-1-benzyl-3-hy­droxy-3-[2-oxo-2-(pyridin-4-yl)eth­yl]indolin-2-one, C22H18N2O3, (Ie), are linked into a three-dimensional framework structure by a combination of O—H⋯N, C—H⋯O and C—H⋯π(arene) hydrogen bonds. (RS)-3-[2-(Benzo[d][1,3]dioxol-5-yl)-2-oxoeth­yl]-1-benzyl-3-hy­droxy­indolin-2-one, C24H19NO5, (If), crystallizes with Z' = 2 in the space group Poverline{1} and the mol­ecules are linked into com­plex sheets by a combination of O—H⋯O, C—H⋯O and C—H⋯π(arene) hydro­gen bonds. In each of (E)-1-benzyl-3-[2-(4-fluoro­phen­yl)-2-oxo­ethyl­idene]indolin-2-one, C23H16FNO2, (IIa), and (E)-1-benzyl-3-[2-oxo-2-(thiophen-2-yl)ethylidene]indolin-2-one, C21H15NO2S, (IIg), the mol­ecules are linked into simple chains by a single C—H⋯O hydrogen bond, while those of (E)-1-benzyl-3-[2-oxo-2-(pyridin-4-yl)ethyl­idene]indolin-2-one, C22H16N2O2, (IIe), are linked by three C—H⋯O hydrogen bonds to form sheets which are further linked into a three-dimensional structure by C—H⋯π(arene) hydrogen bonds. There are no hydrogen bonds in the structures of either (E)-1-benzyl-3-[2-(4-meth­oxy­phen­yl)-2-oxo­ethyl­idene]indolin-2-one, C24H19NO3, (IIc), or (E)-1-benzyl-5-chloro-3-[2-(4-chloro­phen­yl)-2-oxo­ethyl­idene]indolin-2-one, C23H15Cl2NO2, (IIh), but the mol­ecules of (IIh) are linked into chains of π-stacked dimers by a combination of C—Cl⋯π(arene) and aromatic π–π stacking inter­actions.

Introducing drone operations into the nation’s airspace can provide substantial benefits to society, such as preventing derailments, inspecting cell phone towers, delivering medical devices to patients in cardiac distress, and assisting firefighters, says a new congressionally mandated report by the National Academies of Sciences, Engineering, and Medicine.

A cache of exquisitely preserved bones, found in a coal mine in the state of Gujarat, India, appear to be the most primitive primate bones yet discovered, according to an analysis led by researchers from The Johns Hopkins University and Des Moines University. Their assessment of the bones, belonging to ancient, rat-sized, tree-dwelling primates, bolsters the controversial idea that primates native to what is now India played an important role in the very early evolution of primates, mammals that include humans, apes and monkeys.

Linking land and the sea, coastal zones are unique areas, highly diverse in species, habitats and ecosystems and very important to human activities. But there is a mounting stress on these valuable ecosystems from economic, social and environmental pressures. This Thematic Issue presents key pieces of research that demonstrate tools and experiences for achieving more sustainable coastal ecosystems, and highlights that policy action must continue to strive for significantly improved management.

Consumers, manufacturers and government all need to take responsibility for managing the increasing number of waste mobile phones, according to new research. Results indicated that levels of copper, lead, arsenic and mercury released through the disposal of waste phones are potentially toxic to health and the environment.

A recent survey of Dutch mobile phone owners has identified why some consumers buy refurbished mobile phones while others buy new ones. Some consumers perceived refurbished phones to be inferior, which was a major barrier to their purchase. The study’s authors make a number of recommendations to increase consumer uptake of refurbished mobile phones, including promoting the financial and environmental benefits and offering warranties.

Around 50% of gold in used mobile phones is not recovered for future use, a new study finds. The researchers suggest that a global circular economy in mobile phones could be created by improving recycling of precious metals in phones in developing countries, as well as increasing the lifespan of phones and improving collection after use. These changes will reduce pressures on non-renewable resources and close ‘metal flow loops’.

Annual maps of forest cover in Indonesia reveal that, between 2000 and 2008, almost 10 per cent of forest cover on the islands was lost. Around one fifth of this loss occurred in regions where logging is restricted or prohibited. The new maps will help Indonesia meet the objectives of the UN REDD+ programme, which aims to reduce deforestation and forest degradation.

Drones — unmanned aerial vehicles — may be used in close proximity to bird populations without causing disturbance, finds a new study. Drones hold the potential to monitor species and areas that are difficult to reach. The authors advise that, when used with caution, drones could become a valuable tool in the monitoring of species, particularly in protected areas.

Farmers could help to maintain populations of bees and other pollinators by sowing inexpensive seed mixes on their land, a new study suggests. Researchers surveyed pollinators visiting study plots in Berkshire, UK, and explored how sowing different seed mixes and using different management techniques affected the flowers produced and the pollinators visiting them.

Low emission zones (LEZs) that restrict old vehicles in city centres may need implementation in combination with other traffic policies to have greater impacts on air quality, according to new research. A study that measured emission levels before and after the introduction of LEZs in five Dutch cities indicated that air pollution concentrations were reduced but not to a statistically significant level.

Citizen scientists have helped to map pollution across the Netherlands using their smartphones. Their results, produced by thousands of volunteers, are presented in a study which shows how a combination of mass participation and smartphone technology can be a powerful approach to environmental monitoring.
