    摘要： Organophosphorus compounds are prepared by reacting an unsaturated compound, such as a striaght-chain, branched or cyclic olefin or a diene having conjugated or nonconjugated double bonds, with a phosphine by a process in which phosphine and/or phosphine-containing compounds are subjected to an addition reaction with the unsaturated compounds in the presence of a solid heterogeneous catalyst. Particularly suitable heterogeneous catalysts are zeolites and phosphates.
