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.
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.
