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, 1036738-82-5, name is 1-(Cyclopropylsulfonyl)piperidine-4-carbonitrile, introducing its new discovery. Computed Properties of C9H14N2O2S
The present invention discloses a novel process to prepare 4-substituted 1-Cyclopropane-sulfonyl-Piperidinyl compounds, which are useful intermediates for the preparation of antagonists of CCR5 receptor and therefore useful for the treatment of HIV virus infected mammals. It specifically discloses a novel process to synthesize 4-[4-[(R)-[1-[cyclopropylsulfonyl)-4-piperidinyl](3-fluorophenyl)methyl]-3(S)-methyl-1-piperazinyl]-1-[(4,6-dimethyl-5-pyrimidinyl)carbonyl]-4-methylpiperidine] compounds
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 1036738-82-5 is helpful to your research. Computed Properties of C9H14N2O2S
