A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 224311-51-7, Name is 2-(Di-tert-Butylphosphino)biphenyl, molecular formula is C20H27P. In a Article,once mentioned of 224311-51-7, COA of Formula: C20H27P

The propylene dimerization to 2,3-dimethylbutenes (DMB) by homogeneous catalysts prepared in situ by an alternative method based on the reaction of bis(alpha-nitroacetophenonate)nickel(II) [Ni(naph)2] with different organoaluminum compounds, in the presence of a bulky and basic alkyl phosphine such as tricyclohexylphosphine (PCy3), was described. In particular, the influence of the nature of the organoaluminum co-catalyst as well as of the reaction temperature was studied. The catalysts prepared according to this procedure displayed higher activity at room temperature and in hydrocarbon medium as compared with those obtained by oxidative addition of alpha-nitroacetophenone to bis(1,5-cyclooctadiene)nickel(0) [Ni(cod)2] in the presence of the same phosphine ancillary ligand, turnover frequencies up to 24 800 h-1 being achieved when methylalumoxane (MAO) was used as co-catalyst. Moreover, regio-selectivity values to DMB within the C6 cut higher than 82% were observed under the above conditions. Finally, the regio-selectivity was scarcely influenced by decreasing the reaction temperature below 25C, thus allowing to work at room temperature.
