Description
Изобретение относитс к области . ОКСИМОВ ацетонилдиалкилсульфонийбромидов, которые могут найти применение как физиологически активные вещества.The invention relates to the field. OXYMES acetonyl dialkylsulfonium bromides, which can be used as physiologically active substances.
В литературе отсутствуют данные о синтезе ОКСИМОВ, содержащих в молекуле -сульфониевую icepy. Новые соединени получают оксимированием ацетонилдиалкилсульфонийбромидов гидроксиламином в метиловом спирте по схемеIn the literature, there are no data on the synthesis of oximes containing icepy sulfonium in the molecule. The new compounds are prepared by oximation of acetonyl dialkylsulfonium bromides with hydroxylamine in methyl alcohol according to the scheme

Пример. К 9,8 г (0,049 моль) ацетонилдиметилсульфонийбромида прибавл ют раствор в метиловом спирте 0,052 моль гпдроксиламина основани (из 3,62 г NhbOH НС1 и 2,92 г ) и оставл ют при комнатнойExample. To 9.8 g (0.049 mol) of acetonyldimethylsulfonium bromide, add a solution in methyl alcohol of 0.052 mol of gproxylamine base (from 3.62 g of NhbOH HCl and 2.92 g) and leave it at room temperature.

The residue was layered with 5 ml of dry ethyl acetate and left to crystallize in the evaporator of the refrigerator. The precipitate is filtered off with suction, washed with a mixture of dry ethyl acetate-absolute ethanol (1: 1), and is concentrated in a vacuum desiccator. Yield 4.1 g. Crystallized from absolute ethanol.
