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, 108-47-4, name is 2,4-Dimethylpyridine, introducing its new discovery. 108-47-4
PROCESS FOR PREPARING 2-AMINO-5-CYANOBENZOIC ACID DERIVATIVES
Disclosed is a method for preparing a compound of Formula 1 comprising contacting a compound of Formula 2 with a metal cyanide reagent, a copper(I) salt reagent, an iodide salt reagent and at least one compound of Formula 3 wherein R1 is (NHR3or OR4; R2 is CH3 or Cl; R3 is H, C1-C4 alkyl, cyclopropyl, cyclopropylcyclopropyl, cyclopropylmethyl or methylcyclopropyl; R4 is H or C1-C4 alkyl; X is Br or Cl; and R5, R6, R7, R8 and R9 are as defined in the disclosure. Also disclosed is a method for preparing a compound of Formula 4 wherein R12, R13, R14 and Z are as defined in the disclosure, using a compound of Formula 1 characterized by preparing the compound of Formula 1 by the method disclosed above or using a compound of Formula 1 prepared by the method disclosed above.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.108-47-4, you can also check out more blogs about108-47-4
