Article abstract of DOI:10.1039/c39800000635

Reaction of the electron-rich olefin 2N(Et)C>=>2 with tellurium affords the thermally or photochemically labile Et-cyclo2N(Et)C>=Te which reacts with (M = Cr, Mo, or W) or to yield 2N>Et>> or cis-2N>Et>>; the compound 2N>Et>> is readily detellurated to yield the carbenemetal complex 2N>Et>>; the molecule of the title compound lies on a crystallographic mirror plane with the carbene ligand perpendicular to this plane and Te-Cr = 2.765(4), Te-C_carb = 2.12(2) Angstroem, and angle Cr-Te-C_carb = 96.1(5) deg.
