WebBy exploiting the steric properties of NHC ligands, the authors discovered that the use a bulkier IPr* NHC ligand can disfavour the formation of the π-benzylic-Ni intermediate 272, due to a greater steric repulsion between the aryl substrate and bulkier NHC. This results in the production of a higher proportion of linear boronic esters ... WebApr 12, 2024 · Phosphonates, in particular, can be regarded as isosteres of the corresponding phosphate esters and serve as phosphate mimics in biochemical investigations. 1 The introduction of a phosphonic acid of suitable structure to a biological system in place of a natural phosphate ester provides a potential means of regulating the …
