FIELD: organic chemistry.
SUBSTANCE: invention relates to organic chemistry, namely to a method for producing heterofunctional alkenes of the general formula (1), which can be used in the synthesis of medicinal compounds, polymers, products of the perfume industry, etc. In the formula (1) R1=Alk, Ar, H; R2=Alk, Ar, H; R3=CN; R4=CN, C(O)NH2, C(O)Et, C(NH2)=C(CN)2; R3+R4=-C(O)-NH-C(O)-NH-C(O)-. Method is characterized by the fact that the corresponding aldehyde or ketone and the corresponding methylene active compound in a 1:1 molar ratio are mixed with a previously prepared suspension of 0.15 parts of a nonionic surfactant – alkylamidopropylamine oxide – in distilled water, then the mixture is stirred for 2 h and the resulting product is separated by filtration. (I).
EFFECT: proposed method allows to increase the yield of target heterofunctional alkenes.
