Novel coupling between tricarbonyl(7-azabenzonorbornadiene)iron complexes and cyclohexene to form stereospecifically a (C-5 substituted η^4-cyclohexadiene)Fe(CO)"3 moiety - Sun, C.-H.; Shang, N.-C.; Liou, L.-S.; Wang, J.-C. (Elsevier)
Novel coupling between tricarbonyl(7-azabenzonorbornadiene)iron complexes 1 and cyclohexene occurs thermally and photochemically. Complexes 2 were formed stereospecifically with a yield of 21-34% via C-C bond formation from the exo-face of 7-ABND accompanied by the generation of (^4η-cyclohexadiene)Fe(CO)"3 moieties with Fe(CO)"3 syn to the new C-C bond. At the same time, C-5 of this moiety was functionalized with a bulky 7-ABND heterocycle.
