One-pot dehydrations using phenyl isothiocyanate
-
Add time:09/26/2019 Source:sciencedirect.com
Alcohols undergo dehydration in a one-pot procedure when the alkoxide, formed by treating the starting alcohol dissolved in toluene with NaH, reacts with phenyl isothiocyanate and the resulting sodium carbonimidothioate salt is heated overnight at 200 °C. The phenyl isothiocyanate dehydration yields are comparable to those obtained using the classical two-step Chugaev elimination conditions.
