Transformation of thiosulphonates into α-sulphonyldisulphides, a new class of thioaldehyde precursors
Abstract
Toluene-p-thiosulphonates, RCH2SSO2 Tol (1) where R is an electron-withdrawing group are transformed readily into α-sulphonyldisulphides (2) which, with triethylamine, undergo fragmentation–elimination to give 2 moles of thioaldehydes, RCHS.
