    • Typical experimental procedure: A mixture of 1 (2 mmol) and HEH (2.2 mmol) was refluxed under Ar in xylene (5 mL) for the time listed in Table 2. The solvent was evaporated and the residue was subjected to chromatography on a silica gel column with chloroform as eluent and identified by 1H or 13C NMR and HRMS. Representive spectrum data: compound 2d: 1H NMR (CDCl3, 300 MHz) δ: 7.94 (d, J=7.5 Hz, 2H, 7.42-7.56 (m, 3H, 7.16-7.27 (m, 4H, 3.28 (t, J=7.5 Hz, 2H, 3.04 (t, J=7.5 Hz, 2H, 13C NMR (CDCl3, 75 MHz) δ: 198.8, 139.8, 136.9, 133.2, 129.9, 128.7, 128.6, 128.1, 40.1, 29.4; HRMS calcd for C15H1335ClO 244.0655, found 244.0648; compound 2h: 1H NMR (CDCl3, 300 MHz) δ: 7.94 (d, J=8.7 Hz, 2H, 7.19-7.29 (m, 5H, 6.92 (d, J=9 Hz, 2H, 3.25 (t, J=7.8 Hz, 2H, 3.05 t, J=7.5 Hz, 2H
