obtained by the addition of hypophosphorous acid to Schiff bases of ferrocenecarboxaldehyde. They were subsequently condensed with cholesterol and adenosine to form their cholesteryl and adenosinyl esters. The concurrence reaction of DCC with amine nitrogen atom was observed.

The synthesis of new functionalised 6- and 7-membered NHC (N-heterocyclic carbene) precursors bearing anisidyl or pyridine N-substituents, both symmetrically and non-symmetrically substituted is reported. Their corresponding rhodium(I) and iridium(I) complexes, M(COD)(NHC)Cl, were also prepared and characterised. The unusual Rh(III)/Rh(I) salt, [Rh(η2-NHC-py)2Cl2][Rh(COD)Cl2], was obtained with one
method for the synthesis of novel five- and six-membered cyclic formamidinium salts bearing an unsaturated backbone through Cu(II)- or Ag(I)-catalyzed amination of N-alkynyl formamidines. Cu(II)- or Ag(I)-promoted cyclization in a stoichiometric mode was also investigated, and it could offer some desirable cyclic formamidinium salts, which cannot be prepared through a catalytic reaction mode. Two rhodium(I)
