Synthesis of a stable sulfenic acid, trans-decalin-9-sulfenic acid

Abstract

Hydrolysis of trans-9-decalyl methoxymethyl sulfoxide with 7% perchloric acid in MeOH–H2O (2 : 1) gave crystalline trans-decalin-9-sulfenic acid whose structure was confirmed by IR, NMR and mass spectrometry; addition to methyl propiolate affording methyl trans-3-(trans-9-decalylsulfinyl)acrylate.
