Popis:	A series of Te-1-acylmethyl carbotelluroates was prepared in good isolated yields from the reaction of potassium carbotelluroates with α-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 α-haloaceto oximes gave O-acyl oximes in 50−70% yields via Te-1-iminomethylcarbotelluroates.
