| Abstract: | The reaction of 2,3 -pyridinediamine 1a and its 5-bromo analogue 1b, independently, with acetonylacetone leads to the formation of 1:1 condensation products irrespective of the molar ratios employed. The condensation products have been assigned 2-amino 2a and 5-bromo-2-amino-3(2',5'-dimethylpyrrolyl)pyridine 2b structures. Authentic chemical evidence is given in support of the claim for these structures ruling out the equally probable alternative structure 3 for these compounds. Attempted studies on the reactivity of the latter compounds towards electrophilic reagent such as acetic anhydride, benzoylchloride, and arylsulphonyl chlorides have been described. |
