| titleOfInvention | The preparation method of double phosphorus ligand |
| abstract | The present invention relates to a preparation method of bisphosphorus ligand. In the preparation method of bisphosphorus ligand, compound (1) is reacted with metal magnesium to prepare compound (2); compound (3) is reacted with pentachloride Phosphorus is subjected to a first substitution reaction to prepare compound (4); then compound (2) is subjected to a second substitution reaction with compound (4) to prepare compound (5); finally, compound (5) is subjected to a reduction reaction to obtain formula ( 6) Bisphosphine ligands shown: the process is simple, the raw materials are simple and easy to obtain, the process conditions of the preparation process are easy to control, and there is no need to prepare phosphorus-hydrogen intermediates, and the bisphosphine ligands can be prepared under relatively mild process conditions. It is beneficial to the large-scale production of bisphosphine ligands. |
