Monofluorovinyl Tosylate: A Useful Building Block for the Synthesis of Terminal Vinyl Monofluorides via Suzuki−Miyaura Coupling

Abstract

Monofluorovinyl tosylate was developed as a practical vinyl fluoride building block to couple with a variety of arylboronic acids in the presence of a palladium catalyst. The high stereoselectivity of 2-aryl-1-fluoroethene derivatives was achieved. This approach is also applicable to the synthesis of 2,2-diaryl-1-fluoroethenes in good yields.
