Open Data Verified Data

1. Esterification reaction

4,4 '- Dichloromethylbiphenyl was esterified with triethyl phosphite at 160 ° C to obtain 4,4' - bis (diethylphosphonyl methyl) biphenyl.

2. Condensation reaction

4,4 '- bis (diethylphosphonyl) biphenyl is uniformly mixed with dimethyl sulfoxide and sodium benzaldehyde orthosulfonate. Sodium methoxide is used as a catalyst for condensation reaction at 45-50 ℃, and the product is obtained after treatment.
