The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.224311-51-7, Name is 2-(Di-tert-Butylphosphino)biphenyl, molecular formula is C20H27P. In a Article，once mentioned of 224311-51-7, Formula: C20H27P
Recently we have published [M. Arroyo et al., J. Organomet. Chem. 599 (2000) 170] the first results of this project about the thermolysis reactions of [Os(SR)3(PMe2Ph)2], R=C6F5 (complex 1a) or C6F4H-4 (complex 1b) in refiuxing toluene. These reactions afford [Os(SC6F5)2(o-S2C6F 4)(PMe2Ph)] 2a and [Os(C6F5)2(o-S2C6F 4)(PMe2Ph)2] 3a from 1a or [Os(SC6F4H-4)2(o-S2C 6F3H)(PMe2Ph)] 2b from 1b, through processes involving C-F and C-S cleavage as well as rearrangement of C-S bonds. The single crystal diffraction structures of 1a, 2a and 3a have been determined. In the solid state compound 1a shows a C-F-Os interaction. NMR 1H, 31P{1H} and 19F structural studies in solution were also carried out. To analyse the thermolysis reaction varying the basicity of the phosphine ligand, the relation thiolate:phosphine and the oxidation state of osmium atom we have already prepared the new pentacoordinated polifluorobenzothiolate-osmium complexes, [Os(SC6F5)4(P(C6H 4X-4)3)] (X = OCH3, CH3, F, Cl, or CF3).
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: C20H27P, you can also check out more blogs about224311-51-7
