Triphenylphosphane dibromide

Triphenylphosphine dibromide is a chemical compound with a molecular formula of C6H5PBr2. It is an organic phosphorus bromide that is used in the synthesis of organic compounds. Triphenylphosphine dibromide has been shown to have high stability, which can be attributed to its high steric interactions and the presence of two hydroxyl groups. The compound is also used as a catalyst for asymmetric synthesis reactions, such as the enantioselective synthesis of fatty acids and cholesterol esters. Triphenylphosphine dibromide has also been shown to interact with ryanodine receptors, which are responsible for calcium release from intracellular stores in cardiac muscle cells. This interaction may be related to its therapeutic effects on metabolic disorders and autoimmune diseases.

Triphenylphosphine dibromide is used as a reagent for conversion of aldoximes into nitriles. It acts as a reagent for cleavage of acetals. It reacts with amines to give iminophosphoranes. Further, it serves as a reagent in the preparation of alkyl and aryl bromides from alcohols and phenols without rearrangement.
