The oxidation of hydrazones by iodine in the presence of strong organic bases (guanidines) has been studied. Improved yields of vinyl iodides can be obtained by inverse addition using dry solvents and with a final heating period where appropriate. The reaction has been extended to various dihydrazones with interesting results.
已经研究了在强有机碱(胍)存在下碘化对oxidation的氧化作用。可以通过使用干燥溶剂进行逆向添加并在适当的时候进行最终加热来提高碘乙烯的收率。该反应已扩展到各种二hydr,结果令人感兴趣。
