Palladium-Catalyzed Direct C–H Bond Alkynylations of Heteroarenes Using gem-Dichloroalkenes
摘要:
Palladium-catalyzed direct alkynylations of heteroarenes were accomplished with inexpensive gem-dichloroalkenes as user-friendly electrophiles, which set the stage for a modular, step-economical synthesis of diversely decorated heteroaryl alkynes with ample scope.
