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 PhCCH 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.
