RARECHEM AH PB 0207 - Reference Information
| introduction | 3-cyanophenylboronic acid is a light orange powder with a density of 1.25g/cm3, a boiling point of 347.4 c at 760mmHg, and a melting point of 298 c (dec.)(lit.), which can be used as an intermediate in organic synthesis, used in organic synthesis and experimental research. |
| use | 3-cyanophenylboronic acid is an important chemical raw material. 4-cyanophenylboronic acid diol ester generated by reaction with diols such as neopentyl glycol and 1,3-propylene glycol is an important intermediate in the synthesis of medicine and display materials. |
| synthesis method | using 3-cyanobromobenzene as raw material and pinacyl diborate (B2Pin2) as borating agent, 3-cyanophenylboronic acid was prepared under mild reaction conditions through Miyaura borylation reaction, and the effects of different catalysts and bases on the product yield were studied, the products were analyzed and characterized. The synthesis reaction formula is as follows: |
