Organyltellurium trichlorides and diorganyltellurium dichlorides are prepared starting from the electrophilic tellurium tetrachloride (or arylteUurium trichlorides) by ... [Pg.11]

Like vinylic tellurides, acetylenic tellnrides can be prepared by two general approaches, starting respectively from nncleophilic or electrophilic tellurium species. [Pg.107]

Engman describes a similar procedure for the synthesis of dibenzotellurophene but starting from 2,2 -dilithiobiphenyls (18). The cyclization is realized with elemental tellurium, tellurium tetrachloride, or the dichlorotellurolene (19) which acts as a source of electrophilic tellurium. [Pg.754]
