In a Article，once mentioned of 33821-94-2, Synthetic Route of 33821-94-2
A practical protocol for the one-pot synthesis of various aryl sulfonamides, notably of pyridine-core-substituted 7-azaindolyl sulfonamides, is described. A key step is the well-known bromine-lithium exchange reaction of an aryl bromide with tert-butyllithium (t-BuLi). Differing from the common practice to use 2 or more equiv of organolithium, the exact amount of t-BuLi needed for a sufficient exchange reaction is determined for each aryl bromide in a GC-MS-assisted experiment.
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 33821-94-2 is helpful to your research., Synthetic Route of 33821-94-2
