ChemInform Abstract: A New and Efficient Method for the Preparation of S-Phenyl Carbothioates via Mixed Anhydrides Using Active Titanium(IV) Salts

In the presence of a catalytic amount of titanium(IV) salt, various S-phenyl carbothioates are prepared in excellent yields by the reaction of nearly equimolar amounts of silyl derivatives of carboxylic acids and benzenethiols with p-trifluoromethylbenzoic anhydride.
