Base-mediated direct fluoroalkenylation of 2-phenyl-1,3,4-oxadiazole, benzothiazole and benzoxazole with gem-difluoroalkenes†
Abstract
Direct α-fluorovinylation of 2-phenyl-1,3,4-oxadiazole, benzothiazole and benzoxazole with gem-difluoroalkenes via nucleophilic vinylic substitution reaction (SNV) under the assistance of KHMDS or NaH at room temperature is described.
