Tetramethylphosphonium bromide is an organophosphorus compound with the formula (CH3)4PBr. It is a white, water-soluble solid, the salt of the cation tetramethyl phosphonium and the bromide anion. It is prepared by treating trimethylphosphine with methyl bromide.
Deprotonation gives methylenetrimethylphosphine ylide, which can sustain a second deprotonation: [1]
The latter is a precursor to many coordination complexes, e.g., the dicuprous complex Cu2[(Me2P(CH2)22. [2]
