Acyl nitroso compounds may be trapped as eneophiles and Diels-Alder adducts under thermal and transition metal catalyst conditions using nitrodiazomethane, ethyl nitrodiazoacetate and trifluoromethylnitrodiazomethane.
Nitrodiazomethane reacts with olefins in the presence of rhodium(II) acetate to form nitrocyclopropanes. Ab Initio calculations predict that singlet nitrocarbene has little or no barrier to rearrangement to nitrosoformaldehyde.
