NEW MATERIAL:A complex shown by the formula I [p-Tolyl BINAP is 2,2'-bis (di-para-tolylphosphino)-1,1'-binaphthyl of racemic modification or optical active substance; Y is ClO4, PF6, BF4, or PCl6]. EXAMPLE:A complex shown by the formula II. USE:An industrical catalyst for various organic syntheses, asymmetric isomerization reaction, and asymmetric hydrogenation reaction. Having high avtivity and durability. PREPARATION:For example, a rhodium complex shown by the formula III is dissolved in a solbilizing solvent (e.g., TFH, etc.), and hydrogented with an equimolar or excess p-Tolyl BINAP at 10-50 deg.C for 1-10hr.
