Preparation of aryl lsothiocyanates by pyrolysis of N-aryldithiocarbamates
Abstract
Pyrolysis at 180–200° of N-aryldithiocarbamates, prepared from arylamines, affords isothiocyanates in high yield. In contrast to other isothiocyanate syntheses, this method does not require basic conditions or a strongly electron-withdrawing group on the thiol sulphur atom.
