Regioselective, one-pot syntheses of symmetrically and unsymmetrically halogenated 2',6'-bispyrazolylpyridines

A series of regio-selectively 3'-, 4-, 4'-, 4'-, and 5'-halogenated heterocyclic 2',6'-bispyrazolylpyridine derivatives was prepared by a direct halogenation reaction in a simple, one-pot synthesis in good to excellent yield (in gram scale). This methodol

AZO COUPLING KINETICS OF BENZENEDIAZONIUM IONS WITH CITRAZINIC ACID

Azo coupling kinetics of 4-methoxybenzenediazonium ion with 1,2-dihydro-6-hydroxy-2-oxopyridine-4-carboxylic acid (citrazinic acid, Ia) have been measured in dilute solutions of hydrochloric acid and in chloroacetate, ethoxyacetate, acetate, and dihydrogenphosphate buffers.The reaction is subject to general base catalysis, i.e. splitting off of the proton from the tetrahedral intermediate is the rate-limiting step.The rate constants have been measured for the azo coupling reaction with monoanion III (splitting off of the proton from OH group) and dianion.The rate constant with the monoanion III is only 4 x smaller than that with the dianion and practically the same as that with the anion of citrazinic acid ester VIII.The azo coupling rate constants of the monoanion III have been determined for various subtituted benzenediazonium ions, the Q value found is 4.85.
