Cycloaddition reactions of an unsymmetrical α-diazo-β-diketone, 2-diazo-1-phenyl-1,3-butanedione, with a series of imines having various substituents were studied. The results indicated that only cycloadducts derived from acetylphenylketene, which was generated by the thermal Wolff rearrangement of 2-diazo-1-phenyl-1,3-butanedione with phenyl migration, and imines were obtained. © 2002 Wiley Periodicals
研究了不对称 α-重氮-β-二酮、2-重氮-1-苯基-1,3-丁二酮与一系列具有各种取代基的亚胺的环加成反应。结果表明,2-重氮-1-苯基-1,3-丁二酮通过热沃尔夫重排与苯基迁移生成的乙酰苯乙烯酮衍生的环加合物和亚胺类化合物仅能得到。© 2002 Wiley Periodicals, Inc. 杂原子化学 13:165–168, 2002; 在线发表于 Wiley Interscience (www.interscience.wiley.com)。DOI 10.1002/hc.10015
