标题:氰基乙炔的化学.第四部分 氰基-氰胺和相应的氰基-烯胺的制备和反应
摘要:由氰基氯乙炔和二甲基和二乙基胺,哌啶,吗啉和吡咯烷制备的氰基乙胺经酸水解转化为相应的氰基乙酰胺.在三氟化硼-乙醚存在下,用苄基胺或仲胺处理氰基-氨基胺可得到线性氰基-烯胺:与邻氨基苯甲酸甲酯反应可生成3-氰基-4-羟基喹啉衍生物.用醇处理氰基-氰胺,得到氰基(烷氧基)-烯胺.氰基-烯胺和氰基-(烷氧基)-烯胺的酸性水解分别得到氰基乙酰胺和相应的氰基乙酰胺和-乙酸酯的混合物.将二乙基氨基或吗啉代氰基乙炔进行1,3-偶极环加成,生成5-硝基-2-呋喃-乙腈氧化物,得到5-二乙基氨基-和5-吗啉代-3-(5-硝基-2-呋喃基)异恶唑,Nn-二乙基)-和1-(nn-Dimorpholyl)-氰基-烯胺的相同氧化腈.然而,类似地添加氰基(烷氧基)-烯胺,得到了5-O-和5-N-取代的异恶唑的混合物.在三乙胺存在下用甲磺酰氯处理氰基哌啶子基乙炔,得到具有氰基-烯胺型结构的甲基磺酰基甲磺酰氯
