Synthesis, reactivity, and computational studies of the cationic tungsten methyl complex W(NPh)(N2Npy)Me+ and Related Compounds (N2Npy = MeC(2-C5H 4N)(CH2NSiMe3)2)

The synthesis and structure of neutral and cationic tungsten methyl complex was analyzed. The site preferences for the imido and methyl ligands in 2+ and related species were rationalized in terms of π-bonding preferences modified by steric influences. Inclusion of the steric bulk of the silicon manganese groups and the R group on the imido ligand showed that the underlying electronic preference for the imido ligand to be trans to pyridyl can be reversed because of increased steric repulsions. It was observed that increase in steric repulsions caused a misdirection of the amido lone pair π-donation, which in turn destabilizes the metal-imido ligand π-bonding.
