Description
Предложен способ получени р-амниоакроленнов общей NHoCH CRCHO, где R - водород, алкил или арил, исход из замещенных акролеинов ХСН CRCHO, где X - галоид, алкокси, ацилокси , алкоксикарбонатный остаток, заключающийс в том, что исходный замещенный акролеин ХСН CRCHO обрабатывают аммиаком.A method for producing p-amnioakrolennov total NHoCH CRCHO, wherein R - is hydrogen, alkyl or aryl, starting from substituted acroleins CHF CRCHO, wherein X - halogen, alkoxy, acyloxy, alkoksikarbonatny residue, comprising the steps that the original substituted acrolein CHF CRCHO treated with ammonia .
Получаемые ПО описанному способу р-аминоакролеины представл ют интерес дл тонкого хи-мического синтеза, т. к. содержат нар ду с незамещенной аминогруппой весьма ракционноспособную винпльнуюThe obtained software of the described method, p-aminoacroleins, are of interest for fine chemical synthesis, since, in addition to the unsubstituted amino group, they contain very incapable vinplea
Пример. Получение -аминоакролеина Н СН СН-СН О.Example. Getting β-aminoacrolein H CH CH-CH O.
К раствору 2,4 г р-метоксиакролеина в 10 мл спирта прибавл ют по капл м 2,6л(л концентрированного водного раствора аммиака; происходит потемнение реакционной смеси и повышение ее температуры на 10-15°. Раствор исиар ют при комнатной температуре и выдавшие кристаллы промывают смесью 1 вес. ч. абсолютного спирта с 6 вес. част ми ацетона. Кристаллы (0,8 г) имеют т. пл. 105-106°. Из маточного раствора получают дополнительно 0,8 г вещества с т. пл. 102,5- 1035° Общий выход -80% от теоретического. По данным элементарного анализа найдено в %; С-50,73; П-7,02; N-19,96. Дл CsHjON- вычислено в % С-50,69; Н-7,09; N-19,71.To a solution of 2.4 g of p-methoxyacrolein in 10 ml of alcohol is added dropwise 2.6 l (l of concentrated aqueous ammonia solution; the reaction mixture darkens and its temperature increases by 10-15 °. The solution is dried at room temperature and the the crystals are washed with a mixture of 1 part by weight of absolute alcohol with 6 parts by weight of acetone.Crystals (0.8 g) have a melting point of 105-106 ° From the mother liquor, an additional 0.8 g of the substance is obtained with a melting point of pl. 102.5 - 1035 ° Total yield -80% of theoretical. According to elementary analysis, it was found in%; C-50.73; P-7.02; N-19.96. For CsHjON-deduction Sleno in% C-50.69; H-7.09; N-19.71.
Аналогично получают р-амино-а-метилакролеин-n2NCH-C (СНз) - -СН О с выходом 65% от теоретического. Т. пл. 125-127°. По анализу найдено в %: N-16,03. Дл C4H7ON вычислено в % N-16,47.Similarly, p-amino-a-methylacrolein-n2NCH-C (CH3) -CH is prepared in a yield of 65% of the theoretical. T. pl. 125-127 °. According to the analysis found in%: N-16.03. For C4H7ON, calculated in% N-16.47.
