Abstract
Abstract: Vinylation of activated methines is a synthetically useful and challenging transformation. Traditional methods for this transformation always encounter multiple steps, limited generality and/or handling gaseous substrates. Herein, we report by using diphenyl(vinyl)sulfonium triflate as a vinylation component, a one-step direct vinylation of activated methines can be realized under mild conditions. This reaction, compatible with several kinds of activated methines, can lead to the construction of vinylated quaternary carbon centers concisely.
