Source of material

To ethyl ether (150 mL), were added Mg (3.84 g, 0.160 mol) and I2 (1.02 g, 0.004 mol) under the atmosphere of N2. After the mixture was stirred for 10 min, bromobenzene (25 g, 0.160 mol) was added dropwisely. When Mg disappeared, the reaction mixture was refluxed for 30 min and then cooled to −15 °C. To the above solution of PhMgBr was added a solution of 2,4,6-trichloro-1,3,5-triazine (32 g, 0.175 mol) in tetrahydrofuran in 30 min. After 2 h, the reaction was quenched by 20 mL of ethanol. The final mixture was filtered and the filtrate was evaporated to get a yellow solid, which was purified by chromatography on silica gel to get the 2,4-dichloro-6-phenyl-1,3,5-triazine (27.85 g, yield 77%) as a white solid. To the solution of 2,4-dichloro-6-phenyl-1,3,5-triazine (4.52 g, 0.02 mol) in 120 mL of tetrahydrofuran was added K2CO3 (5.52 g, 0.04 mol) and prop-2-yn-1-ol (2.25 g, 0.04 mol). The reaction system was refluxed for 24 h and then filtered to get a brown solution. The solvent was evaporated under reduced pressure to get a yellow solid which was purified by chromatography on silica gel to afford 2-chloro-4-(prop-2-yn-1-yloxy)-6-phenyl-1,3,5-triazine as a light yellow solid. (2.75 g, 52%). 1H-NMR (400 MHz, chloroform-d)): δ [ppm] 7.59(d, J = 8 Hz, 2H), 7.53–7.49 (m, 3H), 5.15 (s, 4H), 2.57 (s, 2H). The crystals were obtained by recrystallization from ethyl acetate at room temperature.

Experimental details

The hydrogen atoms were placed at calculated positions as riding atoms.

Comment

As an important unsaturated unit, the ethynyl group can be used to construct big π-conjugated systems, which can be widely applied into organic electronics, such as high performance organic field-effect transistors [3], [4], organic solar cells [5], organic light-emitting materials [6], organic liquid crystal materials [7] and so on. The s-triazine (1,3,5-triazine) ring is a remarkable building block to generate supramolecular interactions and an important unit to construct various nonlinear optical devices [8]. So designing and synthesizing of novel triazine derivatives with ethynyl conjugated units is a charming direction in organic synthesis. The structure of the title compound was characterized by 1H-NMR and X-ray diffraction.

In the title molecule, the typical bond length [9] of C1—C6, O1—C10, N3—C7 and C11—C12 are 1.3872(19) Å, 1.4451(17) Å, 1.3428(15) Å and 1.167(3) Å, respectively. The torsion angle of C5—C6—C7—N3 is 4°, which demonstrated that the benzene ring and the 1,3,5-triazine ring are not exactly in the same plane (cf. the figure). Similar to the packing of other triazines weak non-classical hydrogen bonds [10] were observed. In the molecular packing, there are obvious π-π stacking interactions between the adjacent aromatic moieties. The distance between adjacent aromatic moieties is less than 3.447 Å.
