The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.7650-91-1, Name is Benzyldiphenylphosphine, molecular formula is C19H17P. In a Article£¬once mentioned of 7650-91-1, Safety of Benzyldiphenylphosphine
ORGANOARSENEVERBINDUNGEN: 39 SUBSTITUERTE BENZYLPHOSPHINE UND -ARSINE ALS LEICHT ZUGAENGLICHE BIDENTATE LIGANDEN
2-Hydroxybenzylamines or 2- and 4-aminobenzylamines react with diphenylphosphine at higher temperature to give hydroxy-substituted and aminosubstituted benzylphosphines, respectively.This reaction fails in the case of alkoxy or dialkylaminobenzyl amines.The corresponding benzylphosphines have been obtained after conversion of the benzylamines into the quaternary ammonium salts and susequent addition of sodium phosphide. 2-Alkylmercaptobenzylphosphines have been synthesized in a similar manner.An elimination-addition-mechanism or a substitution mechanism have been proposed due to the different reaction conditions required.The nitrogen- or oxygen-substituted benzylarsines have been prepared by both reaction paths. 3-Dimethylaminomethyl indole reacts with secondary phosphines or arsines in accordance with the proposed mechanism to give indolylmethyl phosphines and arsines, respectively.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Safety of Benzyldiphenylphosphine, you can also check out more blogs about7650-91-1
