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

dataset for 13C nuclear magnetic resonance spectroscopy (13C NMR) 13C NMR (101 MHz, DMSO-d6, ppm) δ = 164.4 (s, Cq), 161.9 (s, Cq), 150.7 (d, J = 14.1 Hz), 149.5 (bs, Cq), 137.5 (d, J = 8.1 Hz), 136.0 (dd, J = 15.6 Hz, J = 8.4 Hz), 134.4 (dd, J = 11.5 Hz, J = 9.0 Hz), 131.5 (s), 131.0 (d, J = 13.4 Hz), 129.1 (dd, J = 28.8 Hz, J = 3.3 Hz, Cq), 126.1 (bs), 115.8 (dd, J = 21.3 Hz, J = 9.3 Hz), 20.8 (s, 4C, CL(Me)), 20.5 (s, 1C, CL(Me)). Some signals could not be assigned due to low resolution even at 8192 ns (41C). Impurities: 7% DCM, 6% n-pentane, 1% cyclohexane according to the 1H NMR and 3% phosphine oxide according to the 31P NMR.
