The structures of the adducts of dimethylketen with quinoline, isoquinoline, and phenanthridine, and their derivatives have been investigated. In all cases the adduct is formed by cyclo addition of two molecules of dimethylketen across the CN group of the heterocyclic base, to produce derivatives of 3,4,5,6-tetrahydro-2-isopropylidene-5,5-dimethyl-1,3-oxazin-6-one. The structures of the products of
研究了二甲基酮与喹啉,异喹啉和菲啶的加合物的结构及其衍生物。在所有情况下,加合物是通过在杂环碱的C N基团上环加两个分子的二甲基二酮而形成的,以生成3,4,5,6-四氢-2-异亚丙基-5,5-二甲基-1的衍生物,3-oxazin-6-one。已审查的水解和甲醇分解的产物的结构,并在异丙基和亚甲基质子和甲基的磁性非等价的几种情况宝石这些化合物在二甲基基团进行了讨论。描述了加合物的质谱碎片化模式。
