A highlystereoselectivesynthesis of tetrasubstituted monofluoroalkenes with aldehydes and fluorobis(phenylsulfonyl)methane (FBSM) in one pot has been developed. The reaction was amenable to para‐ and meta‐substituted aryl aldehydes, 2‐naphthaldehyde, and cinnamaldehyde, giving phenylsulfonyl‐substituted monofluoroalkenes in 40%–86% yields with 98/2–99/1 Z/E ratios. The presence of the sulfonyl group
