Abstract

The gas-phase decomposition of ethyl, isopropyl, and t-butyl isothiocyanates has been studied in the pressure range of 35–350 mm. The reaction, which has been found to be the unimolecular elimination of thiocyanic acid, is followed by a slow addition of the acid to the olefins to yield mainly the isothiocyanate expected by Markownikoff addition.
