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, 150008-24-5, name is tert-Butyl 4-(hydroxyimino)piperidine-1-carboxylate, introducing its new discovery. Quality Control of: tert-Butyl 4-(hydroxyimino)piperidine-1-carboxylate
An oxime derivative of the formula: STR1 wherein R is a hydrogen atom or a C1-5 alkyl group, R1 is a hydrogen atom, a C1-5 alkyl group or a carboxyl-protecting group, R2 is a hydrogen atom, a halogen atom, a hydroxyl group or an amino group, R3 is a C3-7 cycloalkyl group, R4 is a hydrogen atom, a halogen atom or a C1-4 alkoxy group, each of R5 and R6 which may be the same or different, is a hydrogen atom or a C1-5 alkyl group, or R5 and R6 together represent a C2-4 alkylene group which forms together with the adjacent carbon atom a C3-5 ring, provided that when R2 is a hydrogen atom, R4 is a C1-4 alkoxy group, m is an integer of 0 or 1, and n is an integer of from 1 to 3; or its pharmaceutically acceptable salt.
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 150008-24-5 is helpful to your research. Quality Control of: tert-Butyl 4-(hydroxyimino)piperidine-1-carboxylate
