Diphenylphosphite is an organophosphorus compound 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 α-aminomethylphosphites (aminophosphonates).
