3-dimethylbutan-2-onyl-substituted dimethylammonium salts containing prop-2-ynyl, but-2-ynyl or 3-phenylprop-2ynyl group underwent 3,2-Stevens rearrangement by the action of basic agents to form allenic aminoketones [4]. In the case of the salts containing ethyl, propyl or butyl group instead of methyl moiety the products of both 3,2and 1,2-Stevens rearrangement were obtained. The 3,2-rearrangement product
据文献资料显示,含有prop-2-ynyl、but-2-ynyl或3-phenylprop-2ynyl基团的3,3-二甲基丁-2-壬基取代的二甲基铵盐在碱的作用下发生3,2-Stevens重排。形成丙二烯氨基酮的试剂[4]。在含有乙基、丙基或丁基而不是甲基部分的盐的情况下,获得了 3,2 和 1,2-Stevens 重排的产物。由于氢化物转移,3,2-重排产物部分转化为氢化类似物 [5]。
