Recently I am researching about CHLOROVINYL KETONES; ACYLATION; CHLORIDES; CHEMISTRY, Saw an article supported by the National Research Foundation of Korea (NRF) – Korean government (MSICT) [NRF-2015R1A5A1008958, NRF-2019R1A2C2089953]. Published in AMER CHEMICAL SOC in WASHINGTON ,Authors: Patil, DV; Kim, HY; Oh, K. The CAS is 93-97-0. Through research, I have a further understanding and discovery of Benzoic anhydride. Quality Control of Benzoic anhydride
The photoredox chloroacylation of alkenes has been developed as a substitute for the Friedel-Crafts acylation of alkenes to beta-chloroketones. The direct generation of acyl radical species from acid chlorides under the photoredox conditions allows the formation of beta-chloroketones without dehydrochlorination with the help of KHCO3. The synthetic utility of the current method is demonstrated in the one-pot synthesis of dihydroisoxazole, dihydropyrazole, and dihydropyrimidine-2-thione in 1 mmol scale.
Welcome to talk about 93-97-0, If you have any questions, you can contact Patil, DV; Kim, HY; Oh, K or send Email.. Quality Control of Benzoic anhydride
