Article abstract of DOI:10.1055/s-1997-1181

A new method has been found for generation of nitrile oxides in situ from nitroalkanes under mild conditions. Thus, reaction of nitroalkanes 1 with di-tert-butyl dicarbonate (2) and 4-dimethylaminopyridine (3) as catalyst in the presence of dipolarophiles
