Bis(alkylidynyl)tellurides and ditellurides.

The tellurocarbonylates [M(CTe)(CO)2(Tp*)]- (M = Mo, W; obtained from [M([triple bond, length as m-dash]CBr)(CO)2(Tp*)] and Li2Te or [M([triple bond, length as m-dash]CLi)(CO)2(Tp*)] and Te) react with an additional equivalent of [M([triple bond, length as m-dash]CBr)(CO)2(Tp*)] to give bis(alkylidynyl)tellurides, [M2(μ-CTeC)(CO)4(Tp*)2], whilst oxidation with [Fe(η-C5H5)2]PF6 affords the corresponding ditellurides [M2(μ-CTe2C)(CO)4(Tp*)2]. The unprecedented M[triple bond, length as m-dash]CTeC[triple bond, length as m-dash]M and M[triple bond, length as m-dash]CTe2C[triple bond, length as m-dash]M bridges are discussed with reference to more conventional but rare alkylidynyltelluroethers [M([triple bond, length as m-dash]CTeR)(CO)2(Tp*)] (R = Me, nBu, Ph).
