Abstract

This Account focuses on the palladium-catalysed cross-coupling reactions of pyridazines. The pyridazine moiety is of significant importance in the pharmaceutical as well as the agrochemical field. Synthetic transformations on this moiety, to yield several diverse analogues for a wide array of applications, have received a considerable boost with the advent of palladium-catalysed cross-coupling reactions. These reactions facilitate the direct introduction of suitable groups on the pyridazine nucleus via carbon-carbon or carbon-heteroatom bond formations. This Account presents a brief account of the inherent advantages of palladium chemistry on this moiety followed by seminal work and subsequent developments on this topic.
