Abstract: With radical addition-polar termination (RAPT) cascade as the strategy, efficient cyclopropanation and Giese-type reactions of alkenyl N-methyliminodiacetyl boronates have been realized by means of photoredox catalysis. With chloro- or bromomethyl silicate as the methylene source,… read more here.

Abstract: A visible-light-induced desulfonylative Giese-type reaction has been developed. Essential to the success is the employment of Hantzsch ester to activate benzothiazole sulfones without any heavy-metal additives. Not only benzylic benzothiazole sulfones but also alkyl ones… read more here.
