Eight stable N,N-bis(trimethylsilyl)-1-alkenesulfenamides (3) were synthesized by the reaction of 1-alkenesulfenate anions with TMSCl and LiHMDS. Compounds 3 were isolated either by distillation or by chromatography. 1-Alkenesulfenamides (3) can be desilylated in the presence of aldehydes and ketones that do not bear α-hydrogens, to afford 1-alkenesulfenimines (7) either as single isomers or as mixtures
