Unique carbon–carbon bond homolysis in 3-alkylcyclohexa-1,4-dienyl-3-carboxylic acid radicals
Abstract
3-Substituted cyclohexadienyl radical generated by hydrogen abstraction from 3-alkylcyclohexa-1,4-diene-3-carboxylic acids readily fragment to produce alkyl radicals and benzoic acid; suitably functionalised alkyl groups cyclize in moderate yields.
