The concerted Ag-catalyzed rearrangement of N-indolyl carbonates and esters to afford 3-oxyindole derivatives with broad functional-group compatibility is presented. In addition, this concerted [3,3]-rearrangement approach was expanded to the synthesis of phosphonate and sulfonamide derivatives without the use of an Ag catalyst. Control experiments suggested that no radical pathway is involved at any
