CAS:50889-29-7
Molecular Formula: C24H26BrO2P
Molecular Weight: 457.34g/mol(5-Carboxypentyl)(triphenyl)phosphonium bromide is a type of white crystalline solid. It is soluble in Chloroform and Methanol.
Phosphines (R3P) react with halogens (X2) to phosphonium halides of the type R3PX2. The compound Ph3PBr2 (high melting solid) formed by reaction of triphenylphosphine and bromine is called bromotriphenylphosphonium bromide or dibromotriphenylphosphorane (now defined as a phosphorane) or simply triphenylphosphine dibromide. The dibromide and dichloride are commercially available as halogenation reagents for instance in halogenation of alcohols and phenols .
The compound triphenylphosphine dichloride, Ph3PCl2, is reported as being an ionic compound (PPh3Cl)+Cl− in polar solutions and a molecular species with trigonal bipyramidal molecular geometry in apolar solution and in the solid state.
