Reactions of N,N,N-trialkyl-N-(2,3-dibromo-3-chlorobutyl)ammonium bromides with alcoholic solution of KOH mainly follow the dehydrochlorination pathway, yielding N,N,N-trialkyl-N-(2,3-dibromo-2-butenyl)ammonium bromides as major products. 相似文献

Decomposition of N,N,N,N′,N′,N′-hexamethyl-2,3-dibromo-2-butene-1,4-diammonium diiodide in alcoholic alkali gives ammonium salts containing a 4,4-dialkoxy-2-butynyl group rather than the corresponding 1,4-elimination products. 相似文献

Reaction of bromine with 1,4-bisammonium salts containing, along with a 2-chlorobutenylene common fragment, 4-penten-2-ynyl side groups, as well as of monoammonim salts containing the same side group and a 4-bromo-3-chlorobutenyl group, involve addition of two bromine molecules at each of the side groups, while the double bond of the chlorobutenyl group remains intact. 相似文献

Quaternary ammonium salts containing a 4-penten-2-ynyl group in addition to the alkoxycarbonylmethyl group are synthesized. The surface activity and antimicrobial action of the resulting compounds are studied. 相似文献

The Stevens 3,2 rearrangement of dialkylammonium salts containing, along with 4-penten-2-ynyl, an alkoxycarbonylmethyl group, gives mostly hydrogenated products, with simultaneous dealkylation and aldehyde formation. On acid treatment enamine amino esters give keto esters or their further transformation product, 4-ethyl3-hydroxy-5-methyltetrahydrofuran-2-one. 相似文献
