In 2018,European Journal of Inorganic Chemistry included an article by Hastings, Samantha D.; Cagle, Ethan C.; Totsch, Timothy R.; Tyus, Shakyra D.; Gray, Gary M.. Recommanded Product: 1195-59-1. The article was titled 《Comparative Study of Novel Phosphordiamidite and Phosphite Ligands Used in Alkene Hydroformylation; Synthesis, Characterization, Metalation, and Catalytic Evaluation》. The information in the text is summarized as follows:
Three novel ligands have been prepared by the reactions of 1,1′-(chlorophosphinediyl)bis(1H-pyrrole) with either 2-pyridinemethanol or 2,6-pyridinedimethanol or the reaction of 1,1′-biphenyl-2,2′-diyl phosphorochloridite with 2-pyridinemethanol. Measurement of |1JP-Se| values demonstrate that the phosphite donor is less basic than the phosphoramidite donors. Coordination preferences of the ligands in octahedral cis-tetracarbonylmolybdenum(0) and square planar cis-dichloropalladium(II) complexes have been evaluated using multinuclear NMR and x-ray crystallog. Rhodium(I) complexes of the bidentate ligands have been evaluated as catalysts for styrene hydroformylation, and their activities are nearly double those of catalysts containing traditional phosphites. The regioselectivities of the RhI complexes of the bidentate ligands are not significantly different at 80° and 20 atm and are not affected by the addition of a lithium salt. In contrast, changing reaction conditions causes the % n-aldehyde to vary from 15 to 50%. The regioselectivity of the catalyst containing the bidentate phosphoramidite/pyridine ligand was more sensitive to pressure than temperature with both effects being significant. In the experimental materials used by the author, we found 2,6-Pyridinedimethanol(cas: 1195-59-1Recommanded Product: 1195-59-1)
2,6-Pyridinedimethanol(cas: 1195-59-1) belongs to pyridine. Pyridine derivatives lend themselves to many roles in the spirited field of supramolecular chemistry – whether as the ligand backbone of metal-organic polymers or presiding over the key electronic stations of nanodevices. In biochemistry, pyridine-containing cofactors are necessary nutrients on which our lives depend. Recommanded Product: 1195-59-1
