PYROLYSIS OF 1,2-ETHANEDITHIOL: MICROWAVE SPECTROSCOPIC DETECTION OF VINYL MERCAPTAN, CH2=CHSH

Abstract
Vinyl mercaptan was identified in the thermal decomposition (600–950°C) products of 1,2-ethanedithiol and thiirane. A microwave spectroscopic study of CH2=CHSH and CH2=CHSD showed that the molecule is planar with the total dipole moment of 0.896±0.007 D and has the syn-form.
