Reaction of Potassium Tellurocyanate with 2-Chloroethanol

Reaction of 2-Chloroethanol with potassium tellurocyanate gave a new heterocycle namely 1,3-oxatellura-2-imine 1 in good yield. Halogenation of organotelluride 1 with SOCl2, bromine and iodine gave dichloro, dibromo and diiodo organic tellurium compounds. Treatment of 1 with alkyl halides gave new organic tellurium compounds. Hydrolysis of 1 afford.
