In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. In homogeneous catalysis, catalysts are in the same phase as the reactants. Quality Control of 1,1′-Dibromoferrocene. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. Introducing a new discovery about 1293-65-8, Name is 1,1′-Dibromoferrocene
1,1′-Diaminoferrocene (3) was conveniently synthesized by employing a Gabriel synthesis in two steps starting from 1,1′-dibromoferrocene (1). Compound 1 was reacted with 2.5 equivalents of phthalimide in the presence of Cu 2O using 4-picoline as a solvent to give 1,1′-diphthalimidoferrocene (2) in a moderate yield. Hydrazinolysis of 2 in EtOH afforded 3 in good yields of ca. 70%. The subsequent reaction of 3 with two equivalents of ethyloxalyl chloride in THF gave the diethyl ester of N,N’-ferrocenylene bis(oxamic acid) (1,1′-fcbaH2Et2, 4). The solution obtained by treating 4 with two equivalents of n-Bu4NOH in H2O was added to a solution of Pd(AcO)2 in THF to give the palladium complex [n-Bu 4N]2[Pd(1,1′-fcba)] (5) in ca. 80% yield. The compounds 24 were characterized by 1H, 13CNMR and IR spectroscopy as well as elemental analysis and the heterobinuclear complex 5 by 1H NMR and IR spectroscopy, elemental analysis and by a single-crystal X-ray diffraction study.
A new facile two-step synthetic procedure of 1,1′-diaminoferrocene
