ABSTRACT

New of condensation with simultaneous elimination tertiary butyl groups it is found in reaction of basic hydrolysis of diethyl N-acetylamino-(3,5-di-tert-butyl-4-hydroxybenzyl)-malonate in which result it is formed 2-(3,’5’-di-tert-butyl-4’-hydroxy-phenyl)ethyloxy-p-cresol. The compound constitution is based on the data NMR 1Н and 13С, IR-spectra and synthesis from 5,7-di-tert-butylspiro(2,5)octa-4,7-diene-6-one.
