Unusually ready cleavage of an S–Cα bond in sterically crowded sulphoxides
Abstract
Oxidation of sterically crowded sulphides containing a 2,4,6-tri-t-butylphenyl group or its Dewar benzene analogue affords unusually unstable sulphoxides which undergo ready heterolytic S–Cα cleavage to give indan derivatives and sulphenic acids.
