treated directly with a large excess of the nucleophilic reagents. 2-Chlorocyclooctanone oxime was used in the free state, and 2-chloro-5, 9-cyclododecadienone oxime was first treated with nucleophilic reagents; the resulting α-substituted oximes of the 12-membered ring were hydrogenated to the corresponding saturated oximes with palladium charcoal. These reactions have shown that α-chlorocyclo-alkanone
已经研究了 2-氯环烷酮肟与各种亲核试剂的置换反应,如氨、伯胺和仲胺、银和亚硝酸钠、叠氮化钠、格氏试剂以及来自乙酰丙酮和丙二酸乙酯的碳负离子。8 元和 12 元环的 α-烷基氨基、α-硝基、α-叠氮基和 α-烷基肟的收率很高,而 6 元环的收率适中。已经表明可以用大量过量的亲核试剂直接处理2-氯环己酮肟盐酸盐。2-氯环辛酮肟以游离态使用,2-氯-5,9-环十二碳二烯酮肟先用亲核试剂处理;用钯炭将所得 12 元环的 α-取代肟氢化成相应的饱和肟。这些反应表明 α-氯环烷酮肟具有潜在的合成效用。
