Synthesis and characterization of novel aminophosphine (AMP) ligands and their some transition metal complexes

TITLE: SYNTHESIS AND CHARACTERIZATION OF NOVEL AMINOPHOSPHINE(AMP) LIGANDS AND THEIR SOME TRANSITION METAL COMPLEXESAUTHOR: FEYYAZ DURAPSUMMARYCompounds containing P-N bonds have been known for a few decades. In the presentwork PIII type six multidentate bis(diphenylphosphino) aniline ligands which have P-N-Pframework, were synthesized from the reaction of aniline derivatives namely 2,3-dimethylaniline, 2,4-dimethylaniline, 2,5-dimethylaniline, 2,6-dimethylaniline, 2-ethylanilineand 4-ethylaniline with monochlorodiphenylphosphine (Ph2PCl). PV type chalcogenderivatives (O, S, Se) and Pt(II) ve Cu(I) complexes of these ligands were also prepared.PV and PIII type new aminophosphine compounds derived from ethylenediamineP(O)Ph2NHCH2CH2NHP(O)Ph2, (P(O)Ph2)2NCH2CH2NHP(O)Ph2, (PPh2)2NCH2CH2N(PPh2)2,(P(E)Ph2)2NCH2CH2N(P(E)Ph2)2 (E: O, S, Se) were synthesized. Pt(II) complex of(PPh2)2NCH2CH2N(PPh2)2, were prepared.All of the ligands and their complexes were characterised by NMR, IR, and elementelanalysis. some of the compounds were characterised by X-ray structure analysis.Keywords.
