Source of material

All reagents were obtained from commercial resources. A reference method was used to synthesise FTEB [5]. Under a dry nitrogen atmosphere, 0.218 g 1-iodo-4-methylbenzene (1 mmol), 0.144 g 4-fluorophenylacetylene (1.2 mmol), CuI (0.002 g, 0.01 mmol), and 0.007 g Pd(PPh3)2Cl2 (0.01 mmol) was added successively to a 100 mL Schlenk flask; then 50 mL triethylamine was added. The mixture was stirred for 3 h, then heated at 333 K for 1 h, cooled, and filtered. The filtrate was dried by rotary evaporation, then extracted by hexane. The colorless crystals were obtained from the hexane solution after 6 h, yield 83% (based on 1-iodo-4-methylbenzene).

Experimental details

The structure was solved by direct methods with the SHELXS-2018 program. All H atoms were positioned with idealized geometry (Uiso(H) = 1.2Ueq(C)) using a riding model with C–H = 0.93 Å for benzene and C–H = 0.96 Å for the methyl group.

Comment

Stilbene compounds have a wide range of biological activities. Tolans are known as the most important starting materials to synthesize stilbenes and many F-containing tolans have been reported with their crystal structures [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18]. Here we report the crystal structure of the title compound, an asymmetric tolan, namely, 1-fluoro-4-(p-tolylethynyl)benzene (FTEB). The whole molecule is planar except H atoms from the methyl group. There are two kinds of weak intermolecular forces: C–H…F hydrogen bond and C–H…π, by which a three-dimensional supramolecular structure is created. All the bond lengths of FTEB are similar to the reported results [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18].
