Alkynyltellurolato ligands including a solvatochromic rhenium(<scp>i</scp>) complex
Alkynyltellurolato complexes L<sub><i>n</i></sub>M-Te-CCR (L<sub><i>n</i></sub>M = CpFe(CO)<sub>2</sub>, CpFe(CO)(PPh<sub>3</sub>), Re(CO)<sub>3</sub>(bipy); R = Ph, SiMe<sub>3</sub>) arise <i>via</i> 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 (TeCCR to bipy) charge transfer which is not, however, observed for the lighter analogue [Re(SeCCSiMe<sub>3</sub>)(CO)<sub>3</sub>(bipy)].
