The synthesized compounds were then examined with respect to their substitution reactions with t-butylamine, diethylamine, cyclohexylamine, and trans-1,2-diaminocyclohexane in acetonitrile. In order to determine the mechanism, substituent effect, activation entropy, and nucleophile effect were used as criteria.展开更多
A new radical-mediated method for the synthesis of 1-(2-(1,2-diarylvinyl)phenyl)ethan-1-ones by the redox hydroarylation of o-(hydroxyalkyl)arylalkynes with arylsulfonyl chlorides is described.

This visible light catalysis method proceeds via a sequence of the radical addition of aryl group across the C?C triple bond, protonation and redox reaction, and represents a new redox transformation reaction directed by a neighboring hydroxyl group.展开更多
The Pd-catalyzed homodimerization with respect to arylsulfonyl chlorides as an efficient method for the synthesisof biaryls has been developed.
