Secondary amines add across the free ethynyl group of unsubstituted diacetylenic ketones. Reactions of piperidine with 1-phenylhexa-2,4-diyn-1-one (7), a methyl-substituted derivative, afford 1-phenyl-5-piperidinohex-4-en-2-yn-1-one (17), 3,5-dipiperidinobiphenyl (20), and a diadduct (21); in the presence of water 1-phenyl-3-piperidino-hex-2-ene-1,5-dione (27) is also obtained. Strong solvent-induced
仲胺跨未取代的二炔酮的游离乙炔基加成。哌啶与甲基取代的衍生物1-苯基六-2,4-二炔-1-酮(7)的反应,得到1-苯基-5-哌啶子酮-4-en-2-yn-1-酮(17) ,3,5-二哌啶子基联苯(20)和二加合物(21); 在水存在下,也获得了1-苯基-3-哌啶子基-己-2-烯-1,5-二酮(27)。在加合物的紫外光谱中观察到了高达40 nm的强溶剂诱导的位移。已经获得了一些不稳定的烷基二炔酮[[4] –(6)]。
