Carbon Dioxide → Triphenylphosphane dichloride

Participants

Reaction Steps

In Example 1, 3.36 g (12 millimoles) of triphenylphosphine oxide and 1.54 g (12 millimoles) of oxalyl chloride were dissolved in 50 ml of monochlorobenzene, and the solution was left standing until the evolution of carbon monoxide and carbon dioxide from the solution was completed. A solution of 12 millimoles of triphenylphosphine dichloride in 50 ml of monochlorobenzene was obtained. That is, the conversion of triphenylphosphine oxide to triphenylphosphine dichloride was effected stoichiometrically.
