A general route to C6H6(CO)2Mn-R complexes via C6H6(CO)2Mn-Na+. Alkyl group migrations from manganese to the coordinated arene ring

Article abstract of DOI:10.1021/om00139a038

A convenient and general entry into C₆H₆(CO)₂Mn-R complexes has been achieved via preparation of C₆H₆(CO)₂MnI and reduction in Na/NH₃(l) to yield C₆H₆(CO)₂Mn^- followed by alkylation with R-X (R = -CH₃, -CH₂CH₃, -CH(CH₃)₂, -CH₂C₆H₅, -Si(CH₃)₃, -H). A study of the migration of alkyl groups from manganese to the arene ring to give 6-endo-substituted cyclohexadienyl complexes is reported.
