Facial Synthesis of Sulfinic Esters via Copper-Catalyzed Reaction of Sulfonyl Hydrazides with Alcohols in Air
Publication date: Available online 10 July 2019Source: Journal of Saudi Chemical SocietyAuthor(s): Lingjuan Chen, Jiangxin Pu, Ping Liu, Bin DaiAbstractThe efficient Cu-catalyzed esterification of sulfonyl hydrazides with alcohols in air is described, providing sulfinic esters in good yields and broad scope. Mechanistic studies suggest that the reaction likely proceeds through free-radical formation including arylthio radical and arylsulfonyl radical, while arylsulfuric acid are the major esterification intermediate in this transformation.

Formation of antifouling functional coating from deposition of a zwitterionic-co-nonionic polymer via “grafting to” approach
Publication date: Available online 10 June 2019Source: Journal of Saudi Chemical SocietyAuthor(s): Chaoqun Wu, Yudan Zhou, Haitao Wang, Jianhua Hu, Xiaoliang WangAbstractWe develop a new process for the preparation of synergistic antifouling functional coatings on gold surfaces via a “grafting to” approach. The strategy includes a synthetic step of polymer brushes that consist of poly (ethylene glycol) (PEG) and zwitterionic side chains via a typical reversible-addition fragmentation chain transfer (RAFT) polymerization process, and a subsequent deposition of the polymer brushes onto a gold substrate. The presence of P...
