Rapidreaction between unifunctional molecules and molecules unifunctional at one position and n-functional at another

Abstract

Rate equations for the reaction between A and B, where B is unifunctional, and A is unifunctional at one and n-functional at the other of two independent positions, lead to expressions for the final relative concentrations of the reactants and products in terms of the initial concentrations of A and B, the ratio of the velocity constants at the two positions on A, and the functionality n. These results are applied to the reaction of tryptophane with p-diazobenzenesulphonic acid, in which it appears that the indole group reacts somewhat faster than the amino group.
