A New Method for the Synthesis of Organotellurium Compounds by the Use of Reductive Cleavage of the Tellurium–Tellurium Bond with Lanthanum Metal
efficient reagent for the reductivecleavage of the tellurium-tellurium bond of ditelluride. Alkyl phenyl tellurides were prepared by the reaction of diphenyl ditelluride with primary and secondary alkyl halides in the presence of lanthanum metal and a catalytic amount of iodine in moderate to good yields. The reaction was accelerated by the addition of HMPA. In addition, the reduction of ditelluride with
Treatment of some organotellurium(II) and (IV) compounds with CO in the presence of PdCl2 and LiCl gives aryl and vinylic carboxylic acids in good to high yields; in the case of (Z)-PhChCHTePh the major product was cis-cinnamic acid at 5–50 atm and the trans-isomer at 1 atm CO respectively.
