Abstract
Treatment of orange solutions of Cp*M(NO)(η2-CH2Ph)Cl (M = Mo or W) with an equimolar amount of solid AgBF4in MeCN affords the salts [Cp*M(NO)(η2-CH2Ph)(NCMe)]BF4as analytically pure crystals in good yields. Both orange complexes have been subjected to single-crystal X-ray crystallographic analyses in order to establish their molecular geometries and their intramolecular metrical parameters. Both salts consist of discrete organometallic cations and tetrahedral BF4−anions, the intramolecular dimensions of the two cationic complexes being essentially the same and resembling those found for related Cp*M(NO)-containing compounds. The isolated [Cp*M(NO)(η2-CH2Ph)(NCMe)]+cations are quite electrophilic, being able to abstract Cl−from a NaCl IR cell to revert to their chloro precursors. However, treatment of the [Cp*W(NO)(η2-CH2Ph)(NCMe)]BF4salt with various unsaturated substrates (e.g., diphenylacetylene, 2,3-dimethyl-1,3-butadiene, carbon monoxide, and acetone) in CDCl3results in no detectable chemical reaction. Lewis bases weaker than Cl−evidently cannot displace the acetonitrile ligand from the coordination sphere of the metal or induce the benzyl ligand to diminish its hapticity. Such a diminution does occur for the CH2Ph ligand when the MeCN group in the cationic complexes is replaced by a carboxylate anion to produce neutral Cp′M(NO)(η1-CH2Ph)(η2-O2CR) complexes. The latter complexes are obtainable by treatment of Cp*M(NO)(η2-CH2Ph)Cl with AgO2CR (R = CH(Et)(Ph)) in CH2Cl2and have been fully characterized by conventional spectroscopic methods. Keywords: organomolybdenum, organotungsten, benzyl, cations.
