Ethynylchloromethyl tellurides

The procedure is based on the reaction of lithinm ethynyltellurolates (generated by the successive treatment of acetylenes with n-BuLi and elemental tellnrinm) with iodochloromethane giving ethynylchloromethyl tellurides. Subseqnent reaction with lithinm tellnride forms lithinm(ethynyltelluro) methane tellurolates which cycUze via an intramolecnlar addition of the tellnrolate to the ethynyltelluro moiety. ...
