The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.1038-95-5, Name is Tri-p-tolylphosphine, molecular formula is C21H21P. In a Article，once mentioned of 1038-95-5, Formula: C21H21P
Synthesis and characterization of five new phosphonium salts and related phosphorus ylides of the type R-COCH=PAr3 are reported. The reaction of bromo 4?-methoxo/chloro/nitro acetophenone, alpha-thiophenyl and naphthoyl acetophenone with triphenylphosphine or triparatolylphosphine in acetone gives phosphonium salts. Dehydrogenation of these salts in aqueous sodium hydroxide solution form ylides. Characterization of obtained compounds was performed by IR, 1H, 13C, 31PNMR and elemental analysis.
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.Formula: C21H21P, you can also check out more blogs about1038-95-5
