Thus, in the amido complexes of tungsten, the coordinated ligand has a planar structure and is oriented perpendicularly to the equatorial plane [13,14]. In the complexes with ketimines [39] the ligand is also planar, but is situated in... 

Extensive studies on potential intermediates, kinetic isotope effects, and selectivities have been conducted on the shylamido compoimds. Studies with tungsten alkyl amido complexes have shown that formation of an alkane complex precedes C-H bond cleavage by these d° imido complexes, just as it precedes oxidative addition and a-bond metathesis. ...
