Reactions of [M(CO)<sub>6</sub>) or [M(CO)<sub>3</sub>(MeCN)<sub>3</sub>] (M=Cr, Mo or W) with 4-vinylpyridine lead to the complexes having the formulation [(4-CH<sub>2 </sub>= CH-C<sub>5</sub>H<sub>4</sub>N)M(CO)<sub>3</sub>] (<strong>I</strong>) in which 4-vinylpyridine is bonded to the metal atom through the six π-electrons of the heteroaromatic ring. Reaction of <strong>I</strong> (M = Cr) with HCl gas affords the N-protonated complex [4-CH<sub>2 </sub>= CH-C<sub>5</sub>H<sub>4</sub>NH)Cr(CO)<sub>3</sub> Cl(<strong>II</strong>). Complexes (<strong>I</strong>) (M=Cr or Mo) also react with PPh<sub>3 </sub>to give[M(CO)<sub>3</sub>(PPh<sub>3</sub>)<sub>3</sub>] (<strong>III</strong>). |
