arylpropynes and hydroxylamine hydrochloride through sp3 C–H and C–C bond cleavage has been achieved with DDQ as an oxidant. The mechanistic study shows that the acrylamides are formed through a three-step tandem sequence, including cross-dehydrogenative-coupling (CDC) reaction, aza-Meyer–Schuster rearrangement and Beckmannrearrangement.
