    Abstract: The invention relates to the manufacture of compounds of the formula in which R1 is a secondary or tertiary alkyl group, R2 is an alkyl group, R13 and R14, which may be the same or different, are hydrogen atoms or alkyl, aryl, alkaryl, aralkyl or carbalkoxy groups and R15 is a hydrogen atom, an alkoxy, alkylthioalkyloxy, amino, alkylamino, dialkylamino, alkyl, aryl, alkaryl or aralkyl group or a group in which Z is a straight or branched alkylene group. The compounds are made by additive reaction an appropriate 2,6-dialkylphenol and an unsaturated compound of the formula CH(R13)=C(R14)COR15, the reaction being effected in the presence of a basic catalyst, e.g. a quaternary ammonium base, an alkali-metal amide, alkoxide or hydroxide or an alkaline-earth metal alkoxide or hydroxide, and optionally in a solvent, e.g. a tertiary alkanol, tetrahydrofuran, dimethyl formamide or acetone. The reaction may be effected at 25-200 DEG C. at atmospheric or raised pressure. Examples are given in which (1) 2,6-di-tert.-butylphenol and methyl acrylate yield methyl (3.5-di-tert.-butyl - 4 - hydroxyphenyl) propionate, (2) 2.6-di-tert.-butylphenol and lauryl (or octadecyl) acrylate yield dodecyl (or octadecyl) 3,5 - di - tert. - butyl - 4 - hydroxyphenyl) propionate, (3) 2,6 - di - tert. - butylphenol and diethyl maleate yield diethyl (3,5-di-tert.-butyl - 4 - hydroxyphenyl) succinate, (4) 2.6-di - tert. - butylphenol and acrylamide yield 3,5 - di - tert. - butyl - 4 - hydroxyphenyl propionamide, (5) 2.6 - di - tert. - butylphenol and N - octadecyl acrylamide yield N - octadecyl-3,5 - di - tert. - butyl - 4 - hydroxyphenyl propionamide, (6) 2.6 - di - tert. - butylphenol and methyl vinyl ketone yield 4-(3.5-di-tert.-butyl-4 - hydroxyphenyl) butan - 2 - one, and (7) 2.6 - di - tert. - butylphenol and ethylene bis-acrylate yield ethylene bis(3,5 - di - tert. - butyl - 4 - hydroxyphenyl) propionate.
