| Conventionally, producing an organic phosphor compound, such as alkenylphosphonaic acid ester or akenylphosphine oxides used a substitution reaction employing an organic metal or organic halogen compound as materials. Only certain compounds could be used, because the precise molecular design was difficult. These compounds are highly useful in the synthesis of fine chemicals. They are easily converted to tertiary phosphines, and they themselves can easily react with nucleophilic agents and radical species. They are used in the Horner-Witting reaction. By using this technology, however, organic phosphor compounds are simple, safe, and efficient to produce. Separation, refining, and purification are also easy. Specifically, the process is one of conducting the addition reaction of an easily available secondary phosphine oxide or hydrogen phosphinic acid ester with an acetylene compound with a catalyst containing a Group 9 or 10 metal of the periodic table to thereby obtain the corresponding alkenylphosphine oxide or alkenylphosphinic acid ester.present inventors earnest study reactions easily feasible secondary cyclic phosphonic acid esters acetylene compounds found proceeds presence specific catalyst gives novel alkenylphosphonic yield selectivity based finding Background Alkenylphosphonic skeleton natural products known physiological activity interaction enzyme raw material performing Horner-Emmons carbonyl widely synthesis olefins |
