Abstract

The 62-electron cluster [Ru4(CO)13(μ3-PPh)] (1) reacts with phosphalkynes RCP [(R = tBu, Ar‘ (2,4,6-tBu3C6H2)] to yield a series of unsymmetrically capped bisphosphinidene clusters characterized by a ketene substituted μ4-PR ligand. The reaction pathway was followed by 31P-NMR spectroscopy and reveals that, in the first step of the reaction, a CO substitution of 1 occurs in order to form an ...
