Free NH 3,3-diarylacrylamides are cyclized to substituted 2-quinolones in the presence of CuI, PPh(3), and KO-t-Bu in o-xylene at 100 °C. The reaction proceeds through a C-H functionalization/C-N bond formation process. With unsymmetrical 3,3-diarylacrylamides, high selectivity is observed using substrates
