The 2-chloro-1-dialkylamino-propanes 4a-d are reacted with diphenylacetonitrile under phase transfer conditions to give a mixture of the nitriles 1a-d and 2a-d. Both chloro-dialkylamino-1-phenyl-ethanes 7a-d and 8a-d lead to 4-dialkylamino-2,2,3-triphenyl-butyronitriles 6a-d.
ierung von α‐tert. Aminocarbonsäurehydraziden liefert nur bei dem Pyrrolidin‐Derivat das erwartete 3‐Oxo‐4‐phenyl‐3,4,7,8‐tetrahydro‐2H,6H‐pyrrolo[2,1‐‐c]‐1,2,4‐triazin, wogegen die Piperidin‐ und Hexamethyleniminabkömmlinge, vermutlich unter Spaltung der Dehydrierungsprodukte und Rekombination der Fragmente, Derivate vom Typ des 1,2,4‐Triazin‐5‐ons ergeben, deren Strukturen durch Synthese bestätigt
α-叔的汞 (II) AeDTA 脱氢。氨基羧酸酰肼仅产生预期的 3-氧代-4-苯基-3,4,7,8-四氢-2H,6H-吡咯并[2,1--c]-1,2,4-三嗪吡咯烷衍生物,而哌啶和六亚甲基亚胺衍生物,大概是脱氢产物的裂解和片段的重组,得到 1,2,4-triazin-5-one 型的衍生物,其结构通过合成得到证实。
