Abstract
The kinetics of the Curtius rearrangement of the isomeric 3(4)-azidoca rbonyl-4(3)-methylfuroxans has been studied; CON3 group rearrangement was shown to proceed faster at the 3- versus the 4-position and to be favoured by an electron-withdrawing substituent at the second ring car bon atom; a series of previously inaccessible isomeric aminofuroxans h as been synthesized.
