Diphenylphosphite

Diphenyl phosphite is a diorganophosphite with the formula (C₆H₅O)₂P(O)H. The molecule is tetrahedral. It is a colorless viscous liquid. The compounds can be prepared by treating phosphorus trichloride with phenol. Many analogues can be prepared similarly. One illustrative reaction, diphenylphosphite, aldehydes, and amines react to afford aminophosphonates (Kabachnik–Fields reaction).^[1]
