The reactions of several organosilicon hydrides PhnSiH(4-n), n = 1, 2; R3SiH, R3 = Ph3, Ph2Me, PhMe2, (n-C6H13)3; (p-Me2HSi)2C6H4, with TeCl4 in benzene resulted in the formation of tellurium metal and chlorosilanes in 75-90percent yields.Similar reactions with aryltellurium trichlorides (RTeCl3, R = Ph, p-MeOC6H4, p-EtOC6H4) proceeded in two different ways.On stirring at room temperature for 6-8 h, diaryl ditellurides and chlorosilanes were obtained in 70-95percent yields whereas on refluxing for 6-10 h, tellurium powder and diaryltellurium dichlorides were obtained along withthe chlorosilanes in 80-95percent yields.Diaryltellurium dichlorides (R2TeCl2, R = Ph, p-MeOC6H4) did not react readily with PhSiH3 nor with Ph3SiH.

The reactions of aryltellurium oxochlorides with the lowest aliphatic acid anhydrides lead to diaryltellurium dichlorides, Te, and CO2 through the intermediate formation of diaryltellurium chloride diacylates.Aryltellurium trichlorides and carboxylic acid anhydrides are formed in the reaction with acyl chlorides.The chlorine atom in the tellurium oxochlorides is replaced by a phenyl group on reaction with phenyllithium.The reaction with dimedone in the presence of triethylamine leads to diaryl ditellurides and a product of trimerization of a carbene, viz., a dimedone derivative that is formed in the thermal decomposition of the intermediate ylid.
