Tetraphenylphosphonium bromide cas 2751-90-8 C₂₄H₂₀BrP TPPB

The application of tetraphenylphosphine bromide as a Phasetransfercatalyst is a new technology that has developed in the past two decades. It overcomes the drawback of the need for polar aprotic solvents in heterogeneous organic synthesis chemicalbooks and enables heterogeneous reactions to proceed under relatively mild conditions. Accelerating the reaction rate and increasing the yield have thus played a significant role in promoting the development of organic synthesis.
