This invention is directed to a class of compounds that can be both monodentate and bidentate in their association with a transition metal to form a catalyst for reactions such as the hydroformylation of olefins to produce aldehydes. The compounds contain two phosphorus atoms having different steric and/or electronic nature. In hydroformylation catalysts, the compounds advantageously can produce a variable n/iso product mixture of aldehyde products that can be varied by simply changing process variables such as [H

]/[CO] partial pressure gas ratio or temperature/inert gas partial pressure.
这项发明涉及一类化合物,这些化合物在与过渡金属结合形成催化剂时既可以是一齿的,也可以是二齿的,用于反应如烯烃的氢甲酰化,以产生醛类产物。这些化合物包含两个磷原子,具有不同的空间位阻和/或电子性质。在氢甲酰化催化剂中,这些化合物有利地可以产生可变的n/iso醛类产物混合物,可以通过简单改变过程变量,如[H2]/[CO]分压气体比或温度/惰性气体分压来进行调整。
