1,2-Dichloro-3-iodobenzene → HCID 68707622, compound

Participants

Reaction Steps

1,2-Dichloro-3-iodobenzene (4.39 g, 16.1 mmol), benzylacetylene (1.96 g, 16.9 mmol), copper(I) iodide (26 mg, 0.14 mmol) and bistriphenylphosphinepalladium(II)chloride (113 mg, 0.16 mmol) were combined in triethylamine (100 mL) and heated at reflux for 2 hours. The reaction was allowed to cool to room temperature and then was partitioned between saturated sodium chloride and diethylether. The organic phase was dried with sodium sulfate, filtered, and the filtrate was concentrated under reduced pressure. The residue was purified on silica gel (eluting with hexane) to provide the title compound. MS (DCI/NH3) m/z 278 (M+NH4)+; 1H NMR (CDCl3) δ 3.90 (s, 2H), 7.13 (t, 1H), 7.2-7.5 (m, 7H).
