A novel synthesis of carboxylic acid oxime esters catalyzed by 2-(1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate
We describe a facile synthesis of carboxylic acid oxime esters in acetonitrile from the corresponding carboxylic acids and oximes catalyzed by 2-(1H-benzotriazole-1-yl)-1,1,3,3-tetramethyluronium tetrafluoroborate in the presence of triethylamine at room temperature under mild conditions.

Te-1-acylmethyl and Te-1-iminoalkyl telluroesters: Synthesis and thermolysis leading to 1,3-diketones and O-alkenyl and O-imino esters
A series of Te-1-acylmethyl carbotelluroates was prepared in good isolated yields from the reaction of potassium carbotelluroates with -haloketones in acetonitrile. Thermolysis of the telluroesters afforded vinyl esters in 20-50% yields, while treatment of the carbotellurorates with potassium t-butanolate led to 1,3-diketones in 30-75% yields with the liberation of black tellurium. The reaction of potassium carbotelluroates with -haloaceto oximes gave O-acyl oximes in 50-70% yields via Te-1-iminomethylcarbotelluroates. Copyright Taylor & Francis Group.
