A new, facile, and general synthesis of functional and heterodifunctional ferrocenes.
A new, very simple, and general method for the synthesis of functional and heterodifunctional 1,1'-ferrocenes is reported using the visible-light photolysis of a simple 100-W desk lamp with the easily available complexes [(eta(5)-C(5)H(4)R)Fe(eta(6)-toluene)][PF(6)] (R = Me, Cl, COMe, CO(2)H, CO(2)Me, CO(2)CH(2)CCH, CONHCH(2)Ph) and a substituted cyclopentadienyl salt MC(5)H(4)R' (M = Li, Na, R' = H, COMe, CO(2)Me, SiMe(2)CH(2)Cl, PPh(2)) under ambient conditions. All the reactions give high yields except when the side chain contains a strong ligand competing with the Cp anion complexation.
