The synthesis and addition of azide-substituted a-diazo amides such as N-(4-azidophenyl)-a- diazoacetamide and N-(4-azido-2-hydroxyhenyl)-a-diazoacetamide to olefins and alcohols using either rhodium (I1) acetate or preferably rhodium (I1) pivalate provided cyclopropanecarboxamides and a-alkoxy amides, respectively, without disrupting the azide functionality. These azide-bearing a-diazo amides are potentially useful in the preparation ...
