We report a new synthetic sequence for the preparation of silylated 2,2-difluorostyrene derivatives. This new route has numerous advantages over the previous one including enhanced scope, higher yields, ease of purification, and significant reduction of the amount of desilylated side-products. An unexpected transformation of a silylated 2,2-difluorostyrene derivative is also presented.
