Ferrocenyl-substituted imine ligands and their reactivity towards Fe2(CO)9; crystal structure of FcC(H)C(H)C(H)NC6H11 and (η4R1C(H)C(H)C(H)NR2)Fe(CO)3 (R1C6H5, R2Fc; R1Fc, R2C6H11, R1R2Fc; Fc(η5-C5H5) Fe(η5-C5H4))
摘要:
The synthesis of l-azadiene Ligands bearing ferrocenyl groups either at the C- or N-terminus or on both sides of the ligand from alpha,beta-unsaturated aldehydes and the corresponding amine is described. The reaction of these imine ligands with Fe-2(CO)(9) produces mononuclear iron complexes of the general formula (eta(4)-1-azadiene) Fe(CO)(3). The molecular structure of one of the I-azadiene ligands as well as those of three iron complexes were determined by X-ray structure analyses. (C) 1998 Elsevier Science S.A. All rights reserved.
