More economically and greener surface modified sewage sludge for carbene insertion of diazo compounds into O–H bond of phenols with good yields and high functional group tolerance.
将废水污泥进行经济和环保的表面改性,以较高产率和较高官能团耐受性将重氮化合物插入酚的O-H键。
Silver‐Catalyzed Asymmetric Insertion into Phenolic O−H Bonds using Aryl Diazoacetates and Theoretical Mechanistic Studies
into the O-H bond of phenols was developed. A homobinuclear silver complex with a chiral phosphorous ligand was created in situ from AgNTf2 and (S)-XylylBINAP (in a 2:1 mole ratio). Detailed mechanistic studies using combined experimental and computational techniques revealed that one silver atom center of the catalyst forms a silver carbene and another one works as a Lewis acid for the nucleophilic
