Exposure to a second 0.5 equiv of (Me3CCH2)2Mg.X(dioxane) at higher temperatures produces the dialkyl complexes, Cp*M(NO)(CH2CMe3)2 (2,2{\textquoteright}). Utilizing the two series of Cp*M(NO)Cl2, Cp*M(NO)(CH2CMe3)Cl and Cp*M(NO)(CH2CMe3)2 complexes, the relative electron deficiencies in these 16-electron complexes can be assessed spectroscopically and electrochemically. Without exception, the Mo complexes are the stronger Lewis acids. Also, the mononeopentyl derivatives for both metals are more reactive toward a variety of substrates than are their bis(neopentyl) analogues. Complexes 1 and 1{\textquoteright} serve as precursors to mixed alkyl and alkyl aryl complexes (3, 3{\textquoteright}, 4, 4{\textquoteright}) and yield metal-centered adducts with PMe3 and pyridine (5, 5{\textquoteright}, 6, 6{\textquoteright}). CO and CNCMe3 readily insert into the M-C bonds of 1 and 1{\textquoteright}. The insertion products, Cp*M(NO)(C{E}CH2CMe3)Cl (7, 7{\textquoteright}},

Metathesis of these complexes with 0.5 equiv of another R{\textquoteright}2Mg.x (dioxane) reagent (R{\textquoteright} = CH2CMe3, CH2SiMe3, Me, Ph, o-tolyl) affords a series of 16-electron, mixed alkyl and aryl complexes,; Cp*W-(NO)(R)(R{\textquoteright}), having all ten combinations of R not-equal R{\textquoteright}. These complexes have been characterized by conventional spectroscopic methods. The competitive reactivity of the different tungsten-carbon sigma bonds in these species toward CO insertion has been investigated. Each complex reacts with 1 equiv of CO under ambient conditions to produce the corresponding eta2-acyl complex presumably via an initial carbonyl adduct. An X-ray diffraction analysis of Cp*W(NO)(Ph)-eta2-C{O}CH2CMe3) has been performed to confirm the existence of the eta2-acyl linkage in one of these complexes: space group P2(1)/n},
