Abstract
|
Pd-catalyzed synthesis of urea derivatives from aryl
iodides and different aliphatic and aromatic amines using sodium
azide and chromium hexacarbonyl is described. In this
process, carbonylation of aryl iodides, Curtius rearrangement of aroyl azides, and nucleophilic addition of amines sequentially
occur to afford the products in good to excellent yields. This
protocol is operationally simple and displays a broad substrates
scope.
