13C nuclear magnetic resonance spectroscopy (13C NMR) ()

dataset for 13C nuclear magnetic resonance spectroscopy (13C NMR) 13C NMR (100 MHz, Chloroform-d [77.0 ppm] + TFA, ppm) δ = 145.9 (Cq), 143.0 (Cq), 138.7 (Cq), 137.7 (+, 4C), 132.2 (+, 4C), 130.0 (+, 4C), 129.8 (+, 4C), 124.7 (Cq), 121.5 (Cq), 106.8 (+, 4C), 82.7 (Cq), 80.8 (+, 2C). Missing signals: due to peak broadening and signal overlap, signals (8C) are missing. Impurities: 158.2 (TFA), 157.8 (TFA), 118.1 (TFA), 115.2 (TFA), 112.4 (TFA), 109.5 (TFA).
