Abstract
У роботі синтезовано похідні біс-(гідро-ксибензиліден)-циклоалканонів конденсацією Кляйзена – Шмідта з використанням циклоалканонів та арилальдегідів у присутності HCl як кислотного каталізатора. Реакцію синтезу здійснено в умовах мікрохвильового опромінення. Будову синтезованих сполук визначено методами УФ-, ІЧ-, 1Н ЯМР-спектроскопії. Одержані виходи реакції не були оптимальними через спонтанну полімеризацію п-гідроксибензальдегіду в кислому розчині.
In the present study, bis-(hydroxyben-zylidene)cycloalkanone derivatives were synthesized by Claisen – Schmidt condensation using cycloalkanones and arylaldehydes in the presence of HCl as an acid catalyst. The synthetic reaction was carried out under microwave irradiation. The structure of the synthesized compounds was determined by UV, IR, 1H NMR spectroscopic methods. The obtained reaction yields were not optimal due to the self-polymerization of p-hydroxybenzaldehyde in an acid solution.
