| titleOfInvention | A kind of preparation method of Ir-O-P type catalyst diboronic acid/ester compound |
| abstract | The invention discloses a preparation method of an Ir-O-P type catalyst diboronic acid/ester compound, belonging to the technical field of organic synthesis, comprising the following steps: under air conditions, an Ir metal complex and a phosphine ligand form an active Ir-O -P-type catalyst; under anhydrous and oxygen-free conditions, organic boron source [B], β-N-aromatic (alkane) substrate, and Ir-O-P-type catalyst are added to an organic solvent, and react at 60-120°C, After the reaction is completed, the ar(alkyl) diboronic acid/boronic acid ester compound is obtained through post-treatment. This reaction can obtain ar(alkyl) diboronic acid/boronic acid ester compounds through a one-pot method, which makes up for the limitation of multi-step synthesis and limited substrate scope of such compounds. In addition, in the preparation of aryltriazene-type diborides, the target compound can be obtained in high yield even without adding a ligand. Based on the above advantages, this method also shows very high performance when extended to gram-level reactions. Yield, lay a good foundation for the application in the field of drug synthesis or material development. |
