Treatment of allylic alcohols with thiophosgene and pyridine gives thiolo chloroformates directly at room temperature, presumably via very rapid [3,3] sigmatropic rearrangements of thiono chloroformates. Synthesis of allyl thiono chloroformate from allyl alcohol, sodium hydride and thiophosgene at low temperature and warming up to room temperature supports this finding.
