    摘要: A polymer having bis(diphenylphosphino)binaphthyl groups that can be used as a catalyst for an addition reaction, especially an asymmetric 1,4-addition reaction, or a reduction reaction, especially an asymmetric reduction reaction, and that can be easily recovered and recycled. The polymer having the bis(diphenylphosphino)binaphthyl groups is one resulting from repetition of a racemic or optically active 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl compound substituted at 5-position thereof with an unsaturated terminal of one (meth)acryloyl group of a compound having multiple (meth)acryloyl groups, that another 2,2'-bis(diphenylphosphino)-1,1'-binaphthyl compound of a next unit is substituted at 5'-position thereof with an unsaturated terminal of another (meth)acryloyl group of the compound having multiple (meth)acryloyl groups so as to have a molecular weight of 1500 to 10000. The reduction catalyst comprises this polymer and a transition metal.
