Methanesulfonyl chlonde

On the basis of these findings, the reaction of acyl imines with methanesulfonyl chlonde-triethylamine is not expected to proceed via a sulfene intermediate as previously proposed [99]. Again, a carbanion intermediate accounts nicely for the experimental facts. The electrophihcity of the hetero-l,3-diene is extremely high, therefore the carbanion, formed on reaction of triethylamine with methanesulfonyl chloride, should undergo nucleophilic attack at C-4 of the hetero- 1,3-diene faster than sulfene formation by chloride elimination.
