Investigation of the reaction product of 1,4,7,10-tetraphenyl-cyclododecahexa-1,2,3,7,8,9-ene with dodecacarbonyl-triiron by X-ray diffraction and MS: comparative structural study of the hexacarbonyl-μ2-(1η2-1,2-ene-2η3-3,4,5-allyl-1σ1-5)diiron(FeFe) system
摘要:
Reaction of dodecacarbonyl-triiron with the 12-membered bis(butatriene) results in phenyl ring metallation and an intramolecular crosslinking of the macrocycle with the formation of a system of three condensed rings. The central core of the complex is formed by Fe-2(CO)(6) unit bridged by an organic ligand which is eta(3):eta(1)-bonded by the pi-allylic system and eta(2)-bonded by the olefinic group. The molecular structure of the complex was determined by X-ray diffraction. Differences in fragmentation patterns in MS (EI and LSIMS) were examined. Comparative studies of the geometry of the complex obtained and a series of compounds with isostructural core have been carried out. (C) 1999 Elsevier Science S.A. All rights reserved.
