Investigated catalytic activity of amino and imino phosphine-ru(II) complexes in transfer hydrogen reaction

In this thesis, chiral iminophosphine compounds were synthesized by using alanine and valine aminoalcohol with o-diphenylphosphino benzaldehyde, respectively. The synthesized iminophosphines were reduced by using sodium borohydride to have corresponded aminophosphines. All the ligands react with tetrakis(dimethylsulfoxide)dichlororuthenium(II) to synthesized bisphosphinesdichlororuthenium(II) metal complexes. The structures of all the synthesized compounds were illuminated with FT-IR, C, H, P NMR. The catalytic activities of compounds were tested in transfer hydrogenation reaction with Ruthenium complexes. Transfer hydrogenation were performed with acetophenone and benzophenone derivatives in basic media (NaOH, KOtBu), at 80 centigrade degrees in 2-propanol solvent system. According to the GC analysis the reduction of substrates was high but ee is low.
