In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 255864-58-5, name is tert-Butyl 2-ethynylpiperidine-1-carboxylate, introducing its new discovery. Recommanded Product: tert-Butyl 2-ethynylpiperidine-1-carboxylate
A study concerning the gold(I)-catalyzed rearrangement of propargylic tert-butylcarbamates into 5-methylene-1,3-oxazolidin-2-ones is described. The mild reaction conditions employed allow the efficient synthesis of a variety of these structures, which would be less conveniently obtained using other reported methods. Georg Thieme Verlag Stuttgart.
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 255864-58-5 is helpful to your research. Recommanded Product: tert-Butyl 2-ethynylpiperidine-1-carboxylate
