Abstract:
Novel, very stable ruthenium and osmium containing terminal phosphinidene complexes [( η 6 ‐Ar)(L)MPMes*] (Ar=benzene, p ‐cymene; L=PR 3 , CO, and RNC) have been prepared by dehydrohalogenation of novel [( η 6 ‐Ar)MX 2 (PH 2 Mes*)] complexes in the presence of a stabilizing ligand. Xray crystal structures are reported for [( η 6 ‐C 6 H 6 )(PPh 3 )RuPMes*] ( 9 ) and [( η 6 ‐ p Cy)(PPh 3 )OsPMes*] ( 4 ). Dehydrohalogenation in the absence of a stabilizing ligand resulted in the new Pspiroannulated Ru 2 P 2 ‐ring structure 16 . Dehydrohalogenation in the presence of but‐2‐yne gave a novel phosphaallyl complex [( η 6 ‐Ar)Ru( η 3 ‐R 2 PC(Me)CHMe)] 26 , for which an Xray crystal structure is reported. The mechanism by which 16 and 26 are obtained is presumed to involve the intermediate formation of the 16‐electron ( η 6 ‐benzene)RuPMes* phosphinidene complex.
