摘要
Alkoxo ligands with strong pi-donor character stabilize coordinatively unsaturated organometallic compounds. This is confirmed by the two complexes 2 (each formally 16-electron species), which are in equilibrium with the starting materials When R = tBu, 1 exists in the pure state only under a CO atmosphere, and 2 can even be characterized by X-ray crystallography. R = H, tBu.
