The non-carbonated beverage is sugar- and caffeine-free, and contains 10g of exogenous ketones, which fuel human cells more efficiently than glucose (sugar).

The crystal structure of the sodium salt of mesotrione, namely, catena-poly[[sodium-μ3-2-[(4-methane­sulfonyl-2-nitro­phen­yl)carbon­yl]-3-oxo­cyclo­hex-1-en-1-olato] ethanol monosolvate], {[Na(C14H12NO7S)]C2H5OH}n, is described. The X-ray structural analysis results reveal that the coordination sphere is established by two chelating O atoms, the O atom of the coordinated ethanol mol­ecule, and an O atom from the methyl­sulfonyl group of a neighboring mol­ecule. Simultaneously, an O atom of the cyclo­hexane fragment serves as a bridge to a neighboring sodium ion, forming a flat Na–O–Na–O quadrangle, thereby forming a mono-periodic polymer. The structure displays O—H⋯O hydrogen bonds and C—H⋯O short contacts. Thermogravimetric analysis (TGA) data indicate that the sodium salt of mesotrione decomposes in four stages.

The reaction of [Se8][B12F11NH3]2 with acetone and subsequent crystallization from acetone/diethyl ether yielded the selenium cation [Se(CH2C(O)CH3)3]+ as a by-product, which is stabilized by the weakly coordinating undeca­fluorinated anion [B12F11NH3]−. While attempting to crystallize pure [Se8][B12F11NH3]2, the structure of the isolated product, namely, tris­(2-oxoprop­yl)selenium 1-ammonio­undeca­fluoro­dodeca­borate, was surprising. The cation [Se(CH2C(O)CH3)3]+ represents the first example for a cationic selenium compound with three ketone functional groups located in the β-position with respect to the selenium atom. The cation possesses almost trigonal–pyramidal C3 symmetry and forms hydrogen bonds to the ammonio group of the anion.

The present invention relates to a process for preparing cyclic compounds having at least eight carbon atoms and at least one keto group, to the cyclic compounds obtained by this process and to the use thereof, in particular as fragrance or for providing a fragrance.

The present invention provides aryl ketone compounds and compositions containing them which facilitate the delivery of active agents. The aryl ketone compounds have the formula or a salt thereof, where n=1 to 9, and R1 to R5 are independently hydrogen, C1 to C4 alkyl, C1 to C4 alkoxy, C2 to C4 alkenyl, halogen, hydroxyl, —NH—C(O)—CH3, or —O—C6H5.

Disclosed are novel ruthenium compounds of formula (Ia) and (Ib): wherein R1 and the moiety are defined herein. Also disclosed is a process for using these novel ruthenium compounds as catalysts for asymmetric hydrogenation and transfer hydrogenation of ketones with high reactivities and excellent selectivities.

The present invention provides processes for the preparation of saturated ketone morphinan compounds. In particular, the invention provides processes for the conversion of a morphinan comprising an allyl alcohol ring moiety into a morphinan comprising a saturated ketone ring moiety by an isomerization reaction catalyzed by an inorganic salt of a late transition metal.

The invention relates to a process for producing ketones or hydrocarbon base oil from fatty acids preferably derived from a biological origin or other renewable source. The process is directed at making an aliphatic ketone or a mixture of aliphatic ketones having 14 to 52 carbon atoms, comprising a ketonization reaction of a fatty acid in a vapor phase with a decarboxylation-coupling catalyst to provide ketones, which can be deoxygenated to give saturated hydrocarbons, unsaturated hydrocarbons, and mixtures thereof. Base oils and transportation fuels may be produced from the process herein.
