title: Novel cobalt-catalyzed carbonylation of 2-aryl-2-oxazolines.
abstract: Catalytic ring-expanding carbonylation of 2-aryl-2-oxazolines is reported as a novel method for the synthesis of 4,5-dihydro-1,3-oxazin-6-ones. Various observations suggest the involvement of cobalt radicals as the catalytically active species. [reaction: see text]
