  Novel trivalent organophosphite ligands having the structure of general formula (I): wherein R is an alkyl or aryl group containing 1 to 30 carbon atoms; Ar1 and Ar2 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.

  具有一般式（I）结构的新型三价有机膦配体已经开发出来，其中R是含有1到30个碳原子的烷基或芳基；Ar1和Ar2是含有4到30个碳原子的芳基；R1至R6是H或含有1到40个碳原子的烷基或芳基烃基；X是连接基团或简单化学键。这些配体与Rh金属制备的催化剂溶液显示出对乙烯烯烃基底的羰基化过程非常活跃。这些催化剂溶液在典型的羰基化条件下能够产生线性或支链醛，并表现出不寻常的“配体加速效应”，即随着配体浓度的增加，羰基化活性增加。
