REACTION OF A THIENYL SCHIFF-BASE WITH DIIRON NONACARBONYL - CHARACTERIZATION AND STRUCTURES OF METHYL)-ETA(1)ETA(1)(N)-ANILINO]HEXACARBONYLDIIRON AND METHYL)-ETA(1)ETA(1)(N)-ANILINO]HEXACARBONYLDIIRON

When thienyl Schiff base 1 reacted with Fe-2(CO)(9) under very mild co nditions in benzene three major products were obtained: (1) a cyclomet alated (mu-eta(1):eta(2)-thienyl; eta(1) eta(1)(N))-hexacarbonyldiiron complex, 2, (2) a hexacarbonyldiiron complex with an organic ligand, which is composed of two thienyl moieties derived from the original th ienyl imine and coupled together by a C-C bond, 3, and (3) a hydrogena tion product of the original thienyl Schiff base. Molecular structures of compounds 2b and 3a have been determined by single-crystal X-ray d iffraction.
