Syntheses and Structures of Trimethylphosphine-complexed Primary Boryl Complexes of Group 8 Metals, Cp*M(CO)2(BH2.PMe3) (M = Fe, Ru)

Photolysis of Cp*Fe(CO)2Me in the presence of BH3.PMe3 (1) produced a boryliron complex Cp*Fe(CO)2(BH2.PMe3) (2a). Complex 2a and the ruthenium analogue Cp*Ru(CO)2(BH2.PMe3) (3) were accessible by the salt-elimination reaction between K[Cp*M(CO)2] (M = Fe, Ru) and BH2Cl.PMe3.
