The synthesis of the tetradentate diamidophosphite (L) containing four 1,3,2-diazaphospholidine rings and a porphyrin moiety, its characterization and application in asymmetric Pd-catalyzed reactions  are reported. The best results (up to 63% ee) were obtained for the Pd-catalyzed allylic alkylation of (E)-1,3-diphenylallyl acetate with dimethylmalonate. The complex L[Ru(p-cymene)Cl2]4 was synthesized in situ and characterized by spectroscopic data.  The structure of the compounds obtained is discussed based on 1H, 13C, 13C DEPT, 31P, 1H-13C HSQC, 1H-13C HMBC, 1H-1H COSY, 1H-1H ROESY NMR spectroscopy, as well as UV-Vis and fluorescence spectroscopy.
