ketones (1) do not react. Stereoelectronic factors involved in the reactivity of the rigid cyclopropyl ketone (12) are discussed. The reactions of selected phenolic cyclopropyl ketones have been investigated as anionic counterparts to the acid-catalysed reactions. No reaction is observed.
在各种酸催化剂的存在下,在温和的条件下,芳基环丙基酮(2)环化为1-四氢萘酮(3)。还形成开链甲醇(4)。(3)与(4)的比例取决于芳基环取代基。提出了阳离子机制。环丙基酮(1)不反应。讨论了涉及刚性环丙基酮(12)反应性的立体电子因素。已经研究了选择的酚环丙基酮的反应作为酸催化反应的阴离子对应物。没有观察到反应。
