Amination using N-fluorobenzenesulfonimide (NFSI) as nitrogen source has become an important route to prepare amines. However, there are few methods to prepare N-vinyl sulfonimides using NFSI as nitrogen source. In the presence of Na2HPO4, the hydroamination of propiolates or propiolamides with N-fluorobenzenesulfonimide (NFSI) was realized, where Ag2CO3 and 1,10-phenanthroline derivatives were added as catalysts. It leads to N-vinyldibenzenesulfonimides in high selectivity of Z isomers in the yields of 35%~71%.

Key words: silver carbonate, N-fluorobenzenesulfonimide, N-vinyldibenzenesulfonimide, propiolate, propiolamide
