A new microwave assisted synthesis methodology has been presented for the preparation of the ferrocene amides. Ferrocene carboxylic acid was derivatised using direct 1H-Benzotriazole/SOCl2 methodolgy to prepare N-ferrocenoyl benzotriazole as a new starting material for the functionalization of ferrocene ring. N-ferrocenoyl benzotriazole was reacted with mono- and di-amines under microwave irradiation to prepare ferrocene mono- and di-amides in high purity and in good yield. (C) 2008 Elsevier B.V.

protocol for synthesis of oxy-substituted ferrocenes via cobalt-catalyzed direct C−H alkoxylation under mild conditions. Notably, alcohol serves as an both alkoxide reagent and a solvent. Various ferrocene amides including estrone-derived ferrocene amide are compatible with these reaction conditions. Moreover, control experiments suggested that this alkoxylation might undergo a Co(III)/Co(IV)/Co(II) catalytic

ferrocenoyl derivatives, containing pyridine (1–4) and benzene (5) moieties, were synthesised and characterised. The effect on the spectroscopic and redox properties of these compounds upon addition of H+ was studied, with NMR studies indicating that protonation took place at the pyridine nitrogens of 1–4. A crystal structure determination of the bis(amide) derivative 4 revealed the presence of two intramolecular

The reaction of [(2-Pyridylmethylamino)carbonyl]ferrocene with Cu(ClO4)(2) center dot 6H(2)O under conventional condition in the absence of base affords a monocopper compound, [Cu(Hpmaf)(2)(CH3OH)(2)](ClO4)(2)] 1, while that under solvothermal condition in the presence of triethylamine gives a dicopper compound, [Cu-2(pmaf)(2)](ClO4)(2), (Hpmaf = [(2-Pyridylmethylamino) carbonyl] ferrocene). Both compounds were characterised by elemental analysis, IR and X-ray diffraction analysis. Compound 2 was further characterised by UV-vis and electron paramagnetic resonance (EPR), and the results indicate that it is a fully delocalised mixed-valence dicopper compound. This is the first example of mixed-valence dicopper compound containing ferrocene group. Published by Elsevier B.V.
