The use of acylnitroso compounds of the general formula RCONO as enophiles in the formation of carbon-nitrogen bonds is described. Both inter-and intramolecular ene reactions have been studied. For the intermolecular examples, nitrosocarbonylmethane, thermally liberated from its Diels-Alder adduct with 9, 10-dimethylanthracene, is reacted with various olefins giving the corresponding N-alkylhydroxamic acids in moderate to high ...
