A CONVENIENT SYNTHESIS OF CARBOXANILIDES FROM SILYL CARBOXYLATES AND WEAKLY NUCLEOPHILIC ANILINES USING P-TRIFLUOROMETHYLBENZOIC ANHYDRIDE AND A CATALYTIC AMOUNT OF ACTIVE TITANIUM(IV) SALT

Various carboxanilides are prepared in excellent yields from nearly eq uimolar amounts of silyl carboxylates and the coffesponding weakly nuc leophilic anilines under mild conditions by using p-trifluoromethylben zoic anhydride and a catalytic amount of active titanium(IV) salt.
