A Convenient Synthesis of Carboxanilides from Silyl Carboxylates and Weakly Nucleophilic Anilines Using<i>p</i>-Trifluoromethylbenzoic Anhydride and a Catalytic Amount of Active Titanium(IV) Salt
Various carboxanilides are prepared in excellent yields from nearly equimolar amounts of silyl carboxylates and the corresponding weakly nucleophilic anilines under mild conditions by using p-trifluoromethylbenzoic anhydride and a catalytic amount of active titanium(IV) salt.
