WebJul 2, 2012 · This catalyst system displays a broad applicability that is capable of catalyzing the cross-coupling of aryl bromides, particularly a range of unreactive aryl chlorides, with various types of phosphorus substrates, such as a dialkyl phosphite, diphenylphosphine oxide, and diphenylphosphane. WebJul 24, 2012 · The dialkyl phosphites react with chlorine to give a chlorophosphite. (14.62)(RO)2P (O)H + Cl2 → (RO)2P (O)Cl + HCl They can also be hydrolyzed to give either a monoalkyl phosphite or free H 3 PO 3. A salt that serves as a reactive intermediate is formed by reaction with sodium.
