Cyanomethanesulphonyl chloride has been prepared, and some aspects of its chemistry have been investigated. Reactions with primary and secondary amines led to the expected sulphonamides, but sulphonates derived from reactions with alcohols were in most cases too unstable to be isolated. Reactions with enamines gave either substituted thietan 1,1-dioxides or acyclic sulphones, depending upon whether the enamine was derived
