1H and 13C NMR spectra were recorded at ambient temperature. Chemical shifts are reported relative to SiMe4 and were determined by reference to the residual solvent resonances. The residual 1H NMR resonances for C6D5Cl appear at δ 7.14, 7.00 and 6.97. The 13C NMR resonances for C6D5Cl appear at δ 134.2(s), 129.3(t), 128.3(t), and 126.0(t). All coupling constants are given in Hertz.
