Sultone formation from 2,4,6-tri-isopropylbenzenesulphinic acid
Abstract
2,4,6-Tri-isopropylbenzenesulphinic acid decomposed in the presence of oxygen giving 2,4,6-tri-isopropyl-1,α-sultone; a mechanism involving arylsulphonyl and peroxyarylsulphonyl radicals and intramolecular hydrogen atom abstraction is suggested.
