Eight stable N,N-bis(trimethylsilyl)-1-alkenesulfenamides (3) were synthesized by the reaction of 1-alkenesulfenate anions with TMSCI 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 of geometric isomers about the C=N bond. Protodesilylation of compounds 3 leads to 1-alkenesulfenamides (8) that have only hydrogens on the nitrogen. The parent 1- alkenesulfenamides 8 are not particularly stable, but could be characterized.
PREPARATION AND REACTIONS OF SUBSTITUTED ETHENESULFENATE ANIONS
Schwan, Adrian L.,Refvik, Mitchell D.

Trans-alkyl and gem-silyl substituted ethenesulfenate anions result from the reaction of hexamethyldisilazide bases with anti-alkyl and anti-silyl substituted thiirane-S-oxides, respectively, via a stereoselective deprotonation process.The sulfenates can be captured at sulfur with certain alkyl halides or they can be converted to a series of substituted ethenesulfenic acid amides.
