Ligands can bond with metal central atoms through coordination or covalent bonds, directly affecting the chemical environment around metal atoms, thereby improving reaction conditions, catalytic activity and conversion rates. So far, scientists have developed Thousands of chiral ligands. The SadPhos ligand developed by Professor Zhang Junliang's research group since 2014 is a new type of chiral ligand with adaptive coordination. It has non-C2 symmetry and has the characteristics of a variety of different soft and hard coordination atoms. It can be used as Monophosphine ligands, N,P-ligands, P,S-ligands, P,O-ligands adopt flexible coordination modes with a variety of transition metals and metals with different valence states. After 9 years of continuous development, the SadPhos family has developed from Ming-Phos to Ming-Phos (2014), Xiao-Phos (2015), Wei-Phos (2015), Peng-Phos (2016), Xiang-Phos (2016) , PC-Phos (2017), Xu-Phos (2018), WJ-Phos (2019), Le-Phos (2019), TY-Phos (2020), GF-Phos (2021), W-Phos (2022), Rong-Phos (2023) and other ligands, and relevant results have been published in well-known international magazines Published more than 100 articles. The Ming-Phos ligand is named after Dr. Zhang Zhanming. It is the first Sadphos ligand developed by Professor Zhang Junliang’s research group. It has shown excellent performance in asymmetric reactions catalyzed by transition metals such as gold, copper, silver, and palladium. reflect selectivity.
Bailingwei can provide a variety of Ming-Phos ligands with high purity and more favorable prices in large packages. The structure is identified through hydrogen nuclear magnetic resonance spectroscopy and phosphorus spectroscopy. The quality inspection is strict, and it can provide thousands of asymmetric synthesis supporting products. :

Complete range: covering different series such as chiral ligands, metal catalysts, organic molecular catalysts, chiral building blocks, chiral prosthetic groups, chiral reagents, chiral separation reagents, etc.;
Product frontier: It can provide new chiral ligands and catalysts that can be transformed into the scientific research results of experts and scholars in this field;
Quality assurance: high purity, strict quality control, and stable batch quality.
