Triphenylphosphine hydrobromide is a chemical compound with the molecular formula C18H15PBr. It is a salt derived from triphenylphosphine, which consists of three phenyl groups attached to a central phosphorus atom. The addition of hydrobromic acid to triphenylphosphine produces this hydrobromide salt.
Characteristics ：
Triphenylphosphine hydrobromide is a salt derived from triphenylphosphine, where three phenyl (C6H5) groups are attached to a central phosphorus (P) atom, and it forms a salt with the hydrobromide anion (Br-).
Apply：
Triphenylphosphine hydrobromide is often used in the Wittig reaction, a widely employed method for the synthesis of alkenes. In this reaction, it reacts with an aldehyde or ketone to form a phosphonium ylide, which can then undergo a Wittig rearrangement to produce an alkene.
