Tetraphenylphosphonium bromide (TPPBr), cas:2751-90-8, its synthonyms are as belows: TTB; [Ph4P]Br; Tetraphenylbromophosphine; TetraphenylbromidePHOSPH; FourphenylbroMidephosphine; TetraphenylphosphorusbromiChemicalbookde; tetraphenyl-phosphoniubromide; Tetraphenylphsohoniumbromide; TETRAPHENYLPHOSPHINEBROMIDE; TetraphenylphosphoniuMbroMid; The application of tetraphenylphosphine bromide(TPPBr) can be as a phase transfer catalyst is a new technology developed in the past two decades. It overcomes the disadvantage of requiring polar non proton solvents in heterogeneous organic synthesis and allows heterogeneous reactions to occur under relatively mild conditions, accelerating reaction rates and increasing yields. Therefore, Tetraphenylphosphine bromide(TPPBr) has played a significant role in promoting the development of organic synthesis. Tetraphenylphosphonium bromide (TPPBr), cas: 2751-90-8, has a melting point of 295-300 ℃. Dissolved in alcohol and chloroform, slightly soluble in water.
