A new series of organotellurocyanate containing Ar-COCH(R) groups (i.e., C6H5COCH2TeCN (1), 4-BrC6H4COCH2TeCN 2), 4-PhC6H4COCH2TeCN (3) and C6H5COCH(CH3)TeCN (4)) were prepared by reacting KTeCN with the appropriate α-bromoketone in dry DMSO solution. Treatment of 1, 2, 3 and 4 with 10% NaOH afforded ditellurides 5, 6, 7 and 8 in high yields. Refluxing the ditelluride with activated copper powder in dry dioxane gave the corresponding tellurides (9, 10, 11 and 12) in good yields. Treatment of tellurides with thionyl chloride, bromine and iodine gave the dichloride (13-16), dibromide (17-20) and diiodide (21-24), respectively, in high yields. Both, tellurocyanate (1-4) and ditelluride (5-8) gave the trichloride (25-28), tribromide (29-32) and triiodide (33-36) when reacted with SOCl2, Br2 and I2, respectively. Treatment of 9-16 with m-chloroperbenzoic acid (MCPBA) afforded the corresponding alkyl aryl ketones in fair to good yields. All the compounds were characterized by elemental analysis and spectroscopic data.

α,α-Bis(propiophenone)tellurium dihalides, and pseudohalides, and their adducts with some nitrogen donor molecules have been prepared.Spectral studies (IR and PMR) indicate that while the tetra-coordinated tellurium compounds (I-V) exhibit keto-enol tautomerism (enol form to the extent of ca. 60percent), the hexa-coordinated tellurium compounds (adducts VI-X) exist mainly in the keto form.
