Rh(III)-catalyzed acylmethylation and trifluoroacetic acid (TFA)-mediated nitroso transfer/cyclization cascade reaction in one pot has been developed. The N-nitroso group plays a dual role as a versatile directing group and internal nitrosation reagent. Rh(III)-catalyzed C-H activation/C-C bondformation and TFA-mediated N-N bond cleavage/formation of two C-N bonds are involved in this reaction. This
