Abstract

Microwave-Assisted One-Pot Hydrostannylation/Stille Couplings.-An efficient microwave-assisted one-pot hydrostannylation/Stille coupling protocol is developed. The hydrostannylation can be carried out under Pdcatalyzed or free-radical conditions. A variety of alkynes are coupled with aryl, benzyl and vinyl electrophiles in good yields after total of 8-13 min of microwave irradiation [extreme caution when heating: explosion risk]. -(MALECZKA JR., ROBERT E.; LAVIS, JEROME M.; CLARK, DAMON H.; GALLAGHER, WILLIAM P.; Org.
