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, Product Details of 1038-95-5
New silver(I) derivatives containing triorganophosphines and the anionic dihydrobis(1-imidazolyl)borate [H2B(im)2]-, or the tetrakis(1-imidazolyl)borate ligand, [B(im)4]-, have been synthesized from reaction of AgNO3 with PR3 (R = phenyl, cyclohexyl, o-, m- or p-tolyl) or (PPh2R?) (R? = methyl or ethyl) and K{H2B(im)2}·DMAC [DMAC = dimethytacetamide) or K[B(im)4]. Binuclear [Ag(PR3)2 {(im)BX2(im)}]2 or polymeric [Ag(PR3){(im) BX2(im)}]n (X = H or imidazolate) complexes have been obtained and fully characterized by elemental analyses and FT-IR in the solid state and by NMR (1H and 31P) spectroscopy and conductivity measurements in solution. Solution dam are consistent with partial dissociation of complexes, occurring through breaking of both Ag-N and Ag-P bonds. The structures of [Ag{P(C6H4Me-p)3}2{(im)BH2 (im)}]2·2CHCl3, [Ag{P(cy)3}{(im)BH2(im)}]n and [{P(cy)3}-Ag{(im)B(im)2(im)}]2·MeCN have been determined by single crystal X-ray studies. The [Ag{P(cy)3}{(im)BH2(im)}]n adduct is a single-stranded polymer containing three-coordinate silver atoms (PAgN2 core), while in the two other adducts, the silver atoms are four-coordinate (P2AgN2 cores). In all structures the two silver atoms are bridged by independent imidazolate donors from a pair of (im)BX2(im) moieties.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 1038-95-5 is helpful to your research., name: Tri-p-tolylphosphine
