First Tetradentate Diamidophosphite Based on [5,10,15,20-Tetrakis(4-hydroxyphenyl)porphyrinato]zinc: Synthesis, Spectral Features, Coordination, and Application in Asymmetric Pd-Catalyzed Reactions

Abstract

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)Cl 2 ] 4 was synthesized in situ and characterized by spectroscopic data. The structure of the compounds obtained is discussed based on 1
