  Novel trivalent organophosphonite ligands having the structure of general formula (I): wherein R is an alkyl or aryl group containing 1 to 30 carbon atoms; Ar 1 and Ar 2 are aryl groups containing 4 to 30 carbon atoms; R1 to R6 are H or alkyl or aryl hydrocarbon radicals containing 1 to 40 carbon atoms; and X is a connecting group or a simple chemical bond, were developed and found to be very active for hydroformylation processes for ethylenically unsaturated substrates. Catalyst solutions prepared from these ligands with a Rh metal show an unusual “ligand acceleration effect” for simple alkenes, i.e., the hydroformylation activity increases as the concentration of ligand increases, and are capable of producing linear or branched aldehydes under typical hydroformylation conditions.

  开发了具有一般式(I)结构的新型三价有机磷酸酯配体，其中R是含有1至30个碳原子的烷基或芳基基团；Ar1和Ar2是含有4至30个碳原子的芳基基团；R1至R6是H或含有1至40个碳原子的烷基或芳基烃基团；X是连接基团或简单化学键，发现它们对于乙烯基不饱和底物的氢甲酰化过程非常活跃。使用这些配体与Rh金属制备的催化剂溶液显示出不寻常的“配体加速效应”对于简单烯烃，即随着配体浓度的增加，氢甲酰化活性增加，并且能够在典型的氢甲酰化条件下产生线性或支链醛。
