摘要: Conversion of the Clusters Fe3(CO)9(μ3-η2-N2Et2 and Fe3(CO)9(μ3-NEt)2 into Organic Products The azoalkane-bridged cluster Fe3(CO)9(μ3-η2-N2Et2) (1) its thermal rearrangement product (2) are converted by standard routes derivatives with one carbene ligand C(Ph)OEt (3, 4). Degradation (thermally or oxidatively) these compounds produces diaziridine (5) and/or iminoester EtN = (6). 4 moist p-tolyl isocyanide form indole derivative 8. 1 adds two equiv. alkynes leading to alkyne-bridged 9 ferrole-type clusters 10. The 10, resulting from HCCPh, exist as isomers 10a b which can be equilibrated separated. An alternative route 10 c (alkyne: MeCCMe) starts Fe2(CO)6(C4Me4) treating it Fe2(CO)9 N2Et2. Photolytic oxidative degradation substituted furan 13, pyrrole 14, dihydropyridazine 15. crystal structures 4, 9, 10a, 10b have been determined.
