Abstract

The complex [(η5-MeC5H4)Ru(DPVP)2(CH3CN)]PF6 (4) (DPVP = Ph2PCH[double bond, length as m-dash]CH2) loses CH3CN under vacuum to produce the phosphaallyl complex [(η5-MeC5H4)Ru(η1-DPVP)(η3-DPVP)]PF6 (6) and reacts with Me3SiC[triple bond, length as m-dash]CH and PhC[triple bond, length as m-dash]CH in CH2Cl2–CH3OH solutions to form the methoxymethylcarbene [(η5-MeC5H4)(DPVP)2Ru[double bond, length as m-dash]C(OCH3)(CH3)]PF6 (7) and the carbonyl complex [(η5-MeC5H4)Ru(DPVP)2(CO)]PF6 (8), respectively. In contrast [(η5-MeC5H4)Ru(DPVP)(CO)(CH3CN)]PF6 (15) does not lose CH3CN to form a phosphaallyl complex. The structures of the complexes described herein have been deduced from elemental analyses, infrared spectroscopy, 1H, 13C{1H}, 1H NOE, where appropriate by 31P{1H} NMR spectroscopy and in eight cases by X-ray crystallography.
