Structure and Hirshfeld surface analysis of the salt N,N,N-trimethyl-1-(4-vinyl­phen­yl)methanaminium 4-vinyl­benzene­sulfonate

In the title compound, the asymmetric unit comprises an N,N,N-trimethyl-1-(4-vinyl­phen­yl)methanaminium cation and a 4-vinyl­benzene­sulfonate anion, C12H18N+·C8H7O3S−. The salt has a polymerizable vinyl group attached to both the cation and the anion. The methanaminium and vinyl substituents on the benzene ring of the cation subtend angles of 86.6 (3) and 10.5 (9)° to the ring plane, while the anion is planar excluding the sulfonate O atoms. The vinyl substituent on the benzene ring of the cation is disordered over two sites with a refined occupancy ratio of 0.542 (11):0.458 (11). In the crystal, C—H⋯O hydrogen bonds dominate the packing and combine with a C—H⋯π(ring) contact to stack the cations and anions along the a-axis direction. Hirshfeld surface analysis of the salt and of the individual cation and anion components is also reported.

Synthesis of 7-acetyleno quinone methide derivatives and their application as vinylic polymerization retarders

The invention provides a method for synthesizing 7-Acetyleno quinone methide compounds that is safe and inexpensive. The method avoids the need for extremely cold reaction temperatures and unlike the prior art does not require any highly explosive materials. The method comprises the steps of: a) performing a condensation reaction between 3,5-di-tert-butyl-4-hydroxybenzaldehyde and a secondary amine thereby forming a secondary amine quinone methide intermediate;b) removing water from the secondary amine quinone methide intermediate by azeotropic distillation;c) adding the dehydrated secondary amine quinone methide intermediate to an organic medium containing a metal acetylide to form a Mannich base intermediate; andd) adding a release agent to the Mannich base intermediate to yield a 7-Acetyleno quinone methide.

Celebrate 75 years of Amitabh Bachchan's work with 75 rare vinyl covers


Amitabh Bachchan campaigns for the 1984 elections in Allahabad

Fans across the world celebrated acting legend Amitabh Bachchan's 75th birthday last October. And if you wish to extend the festivities, visit Frames 75, an exhibition of rare photographs and framed memorabilia that celebrate Bachchan's oeuvre.

The exhibition has been curated by film historian and archivist SMM Ausaja and photo journalist Pradeep Chandra. "There were no big commemorative events for his 75th birthday. But we realised that his 75th year is not yet over, so we should celebrate it with a visual journey in his platinum year," says Ausaja.


A photo by Pradeep Chandra of the legend at RK Studios

The duo worked over three months to curate the list of exhibits and even commissioned artwork for the exhibition. "We wanted something rare that's not on the Internet. You will see a photo from his first photo session, a pamphlet from his Allahabad election campaign, and artist Sonu Gupta's recreation of a painting by MF Husain that depicts the three phases of Bachchan's life," Ausaja says.


An original poster of Yaarana

"I did a similar show on his 61st birthday. So, for this exhibition we wanted to do something different. You will see some never-seen-before images by me, including a photo of Bachchan and Rajiv Gandhi at Indira Gandhi's funeral; a frame of him sitting with Bal Thackeray's shadow in the background; a photo with his daughter, with Dilip Kumar, and one with Rajkumar and Sanjay Dutt in the same frame," adds Chandra.


SMM Ausaja and Pradeep Chandra at Bachchan's residence

Also on display will be original posters, vinyl covers and fake notes used for shoots, many of which have Bachchan's image on them. "We wanted a wide variety of media to break monotony and sustain interest across all frames," Ausaja signs off.
