概要

• 論文の詳細を見る

• The crotononitriles <B>1a–c</B> coupled with arenediazonium salts to yield either the acyclic mono- or dihydrazones depending on coupling reaction conditions. Both mono- and dihydrazones could be cyclized to the corresponding pyridazine derivatives. Direct formation of pyridazines on coupling <B>1b</B> and <B>1c</B> with arenediazonium salts was observed. Structures of reaction products are confirmed by spectral and analytical data.
