| titleOfInvention | A kind of synthetic method of organic phosphorus compound |
| abstract | The invention discloses the synthetic methods of one kind 5,5', 6,6', 7,7', 8,8' octahydros [1,1' dinaphthalene] 2,2' bis- [diphenylphosphines], belong to organic synthesis field.This method through catalytic hydrogenation, esterification, then under palladium catalyst and Phosphine ligands co-catalysis, carries out C P key coupling reactions with diphenylphosphine, obtains target product, yield reaches 35% using dinaphthol as starting material.The present invention has step few compared with the prior art, avoids using high poison reaction raw materials, and it is easy to isolate and purify, and is suitble to industrialized production.The target product being prepared has chiral catalysis and Asymmetrical annular-addition field to have unique catalytic activity, has broad application prospects in medicine and natural products synthesis field. |
