CARBODETELLURATION OF ARYLTELLURIUM(IV) COMPOUNDS: OLEFIN ARYLATION AND AROMATIC COUPLING

Article abstract of DOI:10.1016/S0022-328X(00)96183-7

Aryltellurium(IV) compounds react with olefins to give the corresponding arylated olefins in moderate to quantitative yield in the presence of a palladium(II) salt.The reaction proceeds catalytically with respect to the palladium(II) salt if a suitable oxidant, such as t-butyl hydroperoxide or copper(I) or (II) chloride, is added.In the absence of olefin the corresponding biaryls are formed in moderate yield.Transmetalation of tellurium with palladium is a key step of the reaction.
