anomalous substitution products (2a-c), the related nitrile and ester yields normal substitution products (3a and b) under the same conditions. 1,5,5-Triphenylhydantoin (4a) and a series (5a-8a, 13 and 14) of its derivatives have been prepared starting with 3a and b. Acid hydrolysis of 3a yields, in addition to the normal products (4a and 5a) considerable quantities of the rearranged product 4b. An authentic
与α-氯酰胺1a-c(与N-氰基苯胺钾反应)提供异常的取代产物(2a-c)不同,相关的腈和酯在相同条件下产生正常的取代产物(3a和b)。1,5,5-Triphenylhydantoin(4a)及其系列(5a-8a,13和14)的衍生物已从3a和b开始制备。除正常产物(4a和5a)外,酸水解3a还会产生大量的重排产物4b。已从α,α-二苯基甘氨腈和2-甲硫基1,4,4-三苯基-2-咪唑啉-5开始制备了后者的可靠样品及其一系列衍生物(5b-8b和11) -一(9)。当与氨和碘化铵反应时,除正常的氨解产物7b之外,9还会通过16的明显脱苯作用而生成Dimroth重排产物16以及5,5-二苯基糖基oc啶。讨论了咪唑衍生物4-8,a和b,9、11、13和14的质谱。
