Research output: Contribution to journalArticlepeer-review


The synthesis of the l-tert-butyl-4-carbomethoxypyridinyl radical is described and its properties are compared with the corresponding l-methyl, 1-ethyl and 1-isopropyl radicals. Although the tert-butyl radical appears to be the most stable in pure form and less susceptible to π-mer formation, its chemical reactivity toward bromochloromethane is very similar to that of the other 1-alkyl radicals. The nature of the products of reaction of 1-isopropyl-4-carbomethoxypyridinyl with bromochloromethane has been elucidated.
