Application of 12150-46-8, Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 12150-46-8, Name is 1,1-Bis(diphenylphosphino)ferrocene, molecular formula is C34H28FeP2. In a Article，once mentioned of 12150-46-8
Group 7-12 transition-metal complexes serve as effective catalysts for the regioselective intramolecular hydroamination of aminoalkynes having the general formula RC?C(CH2)n-NH2 (n = 3, R = H, Ph; n = 4, R = H) and of 2-(phenylethynyl)aniline. Primary products are pyrrolidines and piperidines bearing an alpha-alkylidene functionality and 2-phenylindole, respectively. Isomerization yields the corresponding pyrrolines and 1,2-dehydropiperidines. The catalytic properties of the transition-metal complexes depend on the appropriate choice of ligand, solvent, temperature, and counteranion. Principles for identifying the most active transition-metal catalysts for the hydroamination of alkynes and for optimizing the reaction conditions are developed. The X-ray crystal structure of one catalyst, [PdCl(triphos)](CF3-SO3), has been determined.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 12150-46-8 is helpful to your research., Application of 12150-46-8
