Abstract

A novel and highly regioselective two-step homocoupling/cyclization procedure from easily available aryl methyl ketones and hydrazine hydrate was developed for the synthesis of methylthio-substituted pyridazines at room temperature. The method has remarkable advantages owing to the simple substrates, mild reaction conditions, ease of manipulation, good yields and high ­regioselectivity.
