| Abstract: | A simple and convenient route for one-pot synthesis of cyclopentad]pyridazine through 1,3-dipolar cycloaddition of fulvenes and hydrazonyl chlorides is described. The reaction of fulvenes with hydrazonyl chlorides in the presence of silver carbonate smoothly afforded a series of cyclopentad]pyridazines. |
