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, name: Tri-p-tolylphosphine
A series of novel [Pd(acac-O,O?)(P?P)]BF4 and known complexes [Pd(acac-O,O?)(PR3)2]BF4 (P?P = dppm (1), dppp (2), dppb (3), dppf (4); R = Ph (5), p-Tol (6), i-Pr (7); acac = 2,4-pentanedionato) were prepared by the reaction of [Pd(acac-O,O?)(MeCN)2]BF4 (1) with appropriate ligands. Complex 2 was characterized by single-crystal X-ray analysis. Models of the structure and IR wavenumbers assignments of the cations of 1-4 were obtained by DFT calculations. Synthesized complexes were tested as catalysts in the telomerization of isoprene and butadiene with diethylamine. In the case of telomerization of butadiene with diethylamine high catalyst activity (e.g. TOFav = 1940 h-1 and TON up to 17,480 for complex 5) was obtained.
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.name: Tri-p-tolylphosphine, you can also check out more blogs about1038-95-5
