摘要:
Novel and unusual dimerization reaction of alpha-chloroacetoacetanilide under basic reaction condition to give structurally unique 6-oxa-3-azabicyclo[3.1.0]hexane was described. (c) 2008 Published by Elsevier Ltd.
已通过 Japp-Klingemann 反应从适当的 N-芳基-2-氯-3-氧代丁酰胺制备了氧代-N-芳基腙酰氯。标题化合物的结构已通过单晶 X 射线结构测定和 IR 光谱确定固态,并通过 IR、UV 和 1 H 和 13 C NMR 光谱确定在溶液中。结果表明腙酰氯部分采用(Z)-构型形式。在晶体中,氯官能团之间一般存在分子内氢键。
Oxanilo-N-arylhydrazonoyl chlorides have been prepared from appropriate N-aryl-2-chloro-3-oxobutanamides by the Japp−Klingemann reaction. The structures of the title compounds have been established in the solid state by singlecrystal X-ray structure determination and IR spectroscopy, and in solution by IR, UV, and 1 H and 13 C NMR spectroscopy. The results indicate that the hydrazonoyl chloride moiety
