  A process for the minimization of phosphonium ion ligand degradation products formed during reaction of a polyunsaturated olefin or an unconjugated functionalized olefin in the presence of a transition metal-triorganophosphine ligand complex catalyst to form as a product, by-product, or intermediate product a conjugated functionalized olefin having a carbon-carbon double bond conjugated to an a-electron­withdrawing group, such as, an a,ß-unsaturated aldehyde, ketone, ester, acid, or nitrile. The minimization process involves conducting the reaction under selected conditions of conversion, temperature, pressure, or a combination thereof; and/or by selecting a triorganophosphine ligand with a specified steric and/or electronic property. Further, a process for reversion of phosphonium ion ligand degradation product(s) back to useful triorganophosphine ligand(s), the reversion involving treating a reaction product fluid containing the degradation product(s) with an inert gas, hydrogen, synthesis gas, or a mixture thereof under conditions sufficient to regenerate the triorganophosphine ligand(s).

  一种用于在存在过渡金属-三有机膦配体复合催化剂的情况下，通过反应多不饱和烯烃或非共轭官能化烯烃以形成产品、副产品或中间产物的方法，以最小化磷酮离子配体降解产物的过程，所述产物为具有碳-碳双键与α-电子受体基团共轭的官能化烯烃，如α,β-不饱和醛、酮、酯、酸或腈。最小化过程涉及在选择的转化率、温度、压力或其组合条件下进行反应；和/或通过选择具有特定立体和/或电子性能的三有机膦配体。此外，一种将磷酮离子配体降解产物回复为有用的三有机膦配体的方法，该回复涉及用惰性气体、氢气、合成气或二者的混合物处理含有降解产物的反应产物流体，在足以再生三有机膦配体的条件下进行处理。
