✦ Synopsis

Duty1 vinyl tellurides and his-vinyl tellurides furnish vinyllithiurns with retention of configuration in good yields upon treatment with nbutyllithium at -7X*C. Vinylic tellurium species are little investigated. Recently we initiated a systematic study of this class of organnelemental compounds and developed several methods for their preparation 1-Q . In this
