Abstract
A practical and efficient synthesis of imidazoylthiocarbonyl derivatives of highly hindered alcohols was achieved using 1,1′-thiocarbonyldiimidazole in very concentrated mixtures of reagents. More diluted conditions give longer reaction times and the recovery of unreacted starting alcohol.
