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, 23364-44-5, name is (1S,2R)-2-Amino-1,2-diphenylethanol, introducing its new discovery. Quality Control of: (1S,2R)-2-Amino-1,2-diphenylethanol
A series of copper-(Schiff-base) complexes with two chiral centers derived from 1,2-diphenyl-2-amino-ethnaol were synthesized and applied to catalyze the asymmetric cyclopropanation of ethenes with diazoacetates. A mechanism that can explain the observed results was proposed. Some of these complexes were also efficient catalysts for asymmetric cyclopropanation of 1,1-diphenylethene with ethyl diazoacetate, affording high e.e. of up to 98,6 percent. An e.e. of 80,7 percent was achived when no solvent was used.
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 23364-44-5 is helpful to your research. Quality Control of: (1S,2R)-2-Amino-1,2-diphenylethanol
