| titleOfInvention |
Optically active diphosphine compound, method for making the compound, transition metal complex having the compound as ligand and method for making optically active substance by use of the complex |
| abstract |
The present invention provides a ligand for a novel catalyst superior in such characteristics as selectivity (chemoselectivity and enantioselectivity) and catalytic activity in asymmetric synthesis reactions and a ligand for a novel catalyst effective in an asymmetric hydrogenation reaction in particular. The ligand is an optically active diphosphine compound represented by the following formula: orine or bromine atom, and R1 and R2 are each an alkyl group having 1 to 3 carbon atoms. |
