Synthesis and reactions of [Co(RCN){PPh(OEt)2}3{η2-C6H 5PO(OEt)2}]BPh4 derivatives: Strong evidence for η2-coordination of the phenyl ring of the C6H5PO(OEt)2 ligand

Cobalt(I) complexes [Co(RCN)P3{η2-C6H5PO-(OEt) 2}]BPh4 (1; R = Me, Ph; P = PPh(OEt)2) were prepared by allowing [CoClP4]BPh4 compound to react with zinc dust in a cosolvent mixture of nitrile and ethanol. η2-Coordination of the arene ring of the C6H5-PO(OEt)2 ligand was confirmed by 1H and 13C NMR spectra and decoupling experiments. Substitution reactions with CO or isocyanide gave free C6H5PO(OEt)2, RCN, and [Co(CO)2P3]+ Or[Co(RNC)2P3]+ cations. Treatment of 1 with H2 (1 atm), in either the presence or absence of a heterogeneous catalyst, gave the unstable cobalt(III) dihydride derivative [CoH2P3{η2-C6H 5PO-(OEt)2}]+.
