The hydroaminomethylation of long chain alkenes with secondary amines in aqueous/organic two-phase system catalyzed by rhodium catalyst precursor and water-soluble diphosphine ligand BISBIS (sulfonated 2,2'-bis(diphenylphosphinomethyl)-1,1'-biphenyl) was investigated. The result showed that the use of BISBIS improved the reaction activity and especially regioselectivity for linear amine significantly compared with the monophosphine ligand TPPTS [P(m-C6H4SO3Na)(3)] the ratio of linear to branched amine was up to 83.
