The reaction of bis(acyl) tellurides with primary or secondary amines or potassium ethanolate yielded the corresponding tellurocarboxylic acid salts, which are readily oxidized with iodine or benzenesulfonyl chloride to afford novel bis(acyl) ditellurides.
<i>Te</i>-1-Acylmethyl and <i>Te</i>-1-Iminoalkyl Telluroesters: Synthesis and Thermolysis Leading to 1,3-Diketones and <i>O</i>-Alkenyl and <i>O</i>-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.
