Synthèse, caractérisation structurale et propriétés catalytiques de nouveaux composés ferrocéniques

Abstract

Sins the synthesis of novel chiral ligands used as catalysts increased much interest in organometallic chemistry, we decided to develop a new class of thiophosphino ferrocenyl hydrazone and dithionophosphine ligands with planar chirality in order to improve existing reactions as well as inventing new ones in asymmetric synthesis area. In this context, ligands were obtained following defined synthetic pathways, with NMR (1H, 13C, 31P) preliminary characterization of intermediate products at every step in addition to masse higt resolution spectroscopy ESI+ and X ray diffraction on monocristal for our target ligands. Pd(II) Complexes were obtained, by direct mettalation. Pd(II) Complexes have been characterized by NMR spectroscopy and X ray diffraction on monocristal and their coordination chemistry studied. Finally, we carry out some preliminary catalytic tests in Suzuki-Miyaura cross-coupling reaction with the obtained ligands complexes and as a prolongation to our work, we project to do more catalytic investigations.
