摘要
This work describes intermolecular acylfluorination of gem-difluoroenynes using acyl fluorides as both acyl source and fluorine source.Trifluoromethyl-substituted allenones or furans could be selectively achieved via phosphine and silver catalysis.These approaches exhibit high regioselectivity,atom econ-omy and broad functionality tolerance.
