<jats:title>Abstract</jats:title><jats:p>Pyrazine‐2,3‐dicarbonitrile (<jats:bold>1</jats:bold>) reacts with alkyl radicals to give mono‐ <jats:bold>3</jats:bold> and di‐alkylated pyrazine‐2,3‐dicarbonitriles <jats:bold>4</jats:bold>. Similarly 1,3‐dimethyllumazine (<jats:bold>2</jats:bold>) reacts with alkyl radicals to give 7‐alkyl‐1,3‐dimethyllumazines <jats:bold>8</jats:bold> as the major product. The reactivity of alkyl radicals decreases in the order tertiary, secondary, and primary, and <jats:bold>1</jats:bold> is more reactive than <jats:bold>2</jats:bold> in those radical substitution reactions.</jats:p>
