Abstract

Alkynyltellurolato complexes L_nM-Te-C = CR (L_nM = CpFe(CO)₂, CpFe(CO)(PPh₃), Re(CO)₃(bipy); R = Ph, SiMe₃) arise via tellurium insertion into alkynyllithiums followed by metathesis with the corresponding metal halide complex. The rhenium(i) complex displays solvatochromism (hypsochromic shift in polar solvents) for the inter-ligand (TeC CR to bipy) charge transfer which is not, however, observed for the lighter analogue [Re(SeC CSiMe₃)(CO)₃(bipy)].
