Regioselective nucleophilic additions to (η<sup>6</sup>-benzyl alcohol)tricarbonylchromium: isolation and X-ray crystal structure of the intermediate (η<sup>6</sup>-5-methylene-6-exo-t-butylcyclohexa-1,3-diene)tricarbonylchromium

Treatment of (η6-benzyl alcohol)tricarbonylchromium with alkyl-lithium compounds (ButLi; MeLi-tetramethylethylenediamine; BunLi; PhLi) regioselectively generates the corresponding η6-5-methylene-6-exo-alkylcyclohexa-1,3-diene complexes which undergo proton catalysed isomerisations to give (η6-ortho-alkyltoluene)tricarbonylchromium complexes.
