Notes:
The 1H, 13C and 31P NMR spectra of [Ru(CH2C6H4CH2)(PMe3)3], which contains a coordinated o-xylidene moiety, have been analysed. Parameters such as the geminal coupling in the methylene groups, P,H couplings and the chemical shifts of the quaternary ring carbon atoms all point to a metal-o-xylidene binding that is intermediate between σ2,π and π2. Spectral assignment is assisted by P-H correlation spectroscopy using the COLOC sequence. The best parameter for identifying the bonding mode is the chemical shift for the quaternary aromatic carbon atoms.
