    • General Procedure for the Sonogashira Reaction of Aryl Iodides A mixture of NaOH (0.08 g, 2 mmol, Pd(OAc)2 (2 mg, 1 mol, distilled H2O (3 g, and acetone (3 g, 3.8 mL) was stirred for 5 min. Then, aryl iodides (1 mmol) and terminal alkynes (1.2 mmol) were introduced and the mixture of the reaction was heated to 60°C for 1 h. Afterward, the reaction solution was cooled to r.t. and extracted four times with Et2O (4 x 10 mL, The combined organic phase was analyzed by GC and GC-MS. Further purification of the product was achieved by flash chromatography on a silica gel column. 1-(2-Phenylethynyl)naphthalene (Table 2, entry 6, 1H NMR (500 MHz, CDCl3, TMS, δ, 8.43-8.45 (d, 1 H, J, 8.35 Hz, 7.72-7.80 (m, 3 H, 7.61-7.63 (m, 2 H, 7.55 (m, 1 H, 7.46-7.48 (m, 1 H, 7.33-7.38 (m, 1 H, 7.30-7.32 (m, 3 H, MS (EI, m/z, 229 (20, M, 1, 228 (100, M, 226 43
