Evidence for the radical polymerisation of nitrile groups in polyacrylonitrile has been sought using model compounds. No evidence for the cycloaddition of iminyls to nitrile groups has been obtained but nucleophilic addition occurred easily. Thus, 1,8-dicyanonaphthalene reacted with hydroxylamine to give naphthalimide dioxime and with butyl-lithium to give azaphenalene derivatives but adamantyl radicals
