Synthesis, complexation behavior and application of a new diphosphite ligand in rhodium-catalyzed hydroformylation
Oxidative coupling of 3-(3-tert-butyl-4-hydroxyphenyl)propionic acid methyl ester (2) gave dimethyl 3,3?-(5,5?-di-tert-butyl-6,6?- dihydroxybiphenyl-3,3?-diyl)-dipropionate (1c), which upon phosphorylation/transesterification with a phosphochloridite derived from (R)-binaphthol, formed the new unsymmetrical binaphthol-bridged diphosphite 4. A rhodium catalyst based on 4 as ligand gave predominantly iso-selectivity in the hydroformylation of selected styrenes but opposite regioselectivity with 2,6-disubstituted derivatives. New chelate metal complexes (acac)RhL, PdCl 2L and PtCl2L have been synthesized by reacting 4 with (acac)Rh(CO)2, PdCl2(MeCN)2 and PtCl 2(COD), respectively. The structure of obtained compounds is determined based on 1H, 13C, 31P and 195Pt NMR spectroscopy and mass spectrometry data.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 18531-94-7, help many people in the next few years.name: (R)-[1,1′-Binaphthalene]-2,2′-diol
