Molybdenum
and tungsten alkylidene complexes that contain the sterically
demanding hexaisopropylterphenylimido ligand, N-2,6-(2,4,6-i-Pr3C6H2)2C6H3 (NHIPT), have been prepared from Mo(N-t-Bu)2Cl2(1,2-dimethoxyethane) or
W(N-t-Bu)2Cl2(pyridine)2, employing tert-butylimido ligands as sacrificial
proton acceptors. These complexes include M(NHIPT)(CH-t-Bu)Cl2 (M = Mo, W), Mo(NHIPT)(CH-t-Bu)(pyrrolide)2, and Mo(NHIPT)(CH-t-Bu)(pyrrolide)(OC6F5)(CH3CN). In all cases only anti alkylidene
isomers are observed in solution, as a consequence of the steric demands
of the NHIPT ligand. An X-ray structure of W(NHIPT)(CH-t-Bu)Cl2 showed it to be a monomer with a disordered alkylidene
that is 86% in the anti configuration and 14% in the syn configuration.
