The hydrogenation of avermectin catalyzed by [RhCl(COD)]_2-BISBIS[COD:1,5-cyclooctadiene,BISBIS:sulfonated 1,1'-bis(diphenylphosphino Methyl-2,2'-biphenyl)] in situ in aquenous/organic two-phase system was studied.The influence of various parameters,such as the surfactant concentration,the molar ratio of rhodium to phosphine,the reaction temperature and pressure on this hydrogenation were investigated.The results showed that the hydrogenation activities of diphosphine was higher that of monophosphine.
