amination of arenethrough C–H bond cleavage employing N-fluorobenzenesulfonimide (NFSI) as the amination reagent in good to excellent yields with broad arene scope in the absence of any metal, ligand or additive is reported. Unlike previous transition metal-catalysed aminations in which high reaction temperatures are usually necessary, this novel reaction at room temperature is the first example of C–H

The first Cu(i)-catalyzed cross-couplingreaction by hydrogen (H2) removal for the stereoselectivesynthesis of 3-phosphoindoles is reported. Going beyond the oxidative dehydrogenative coupling reactions reported recently, this reaction completely omits the oxidant and base, producing hydrogen (H2) as the only byproduct.

A direct oxidative C–H amination affording 1-acetyl indolecarboxylates starting from 2-acetamido-3-arylacrylates has been achieved. Indole-2-carboxylates can be targeted with a straightforward deacetylation of the initial reaction products. The C–H amination reaction is carried out using a catalytic Pd(II) source with oxygen as the terminal oxidant. The scope and application of this chemistry is demonstrated
