文摘

Under dual gold/photoredox catalytic conditions, intermediates from the Meyer–Schuster rearrangement underwent an efficient cross-coupling with arene diazonium salts, leading to α-arylated enones. Diazonium salts assisted the dissociation of the propargyl hydroxyl group by forming alkoxydiazenes in the Meyer–Schuster rearrangement, and the coupling was proposed to proceed through an allenyl methyl ether.
