Allyl bromide is a clear to light yellow liquid. As an alkylating agent, allyl bromide is used extensively in the synthesis of polymers, pharmaceuticals, allyls, and other organic compounds. Allyl bromide is a clear liquid with an intense, acrid, persistent smell and is flammable. It is insoluble in water, but soluble in alcohol, aether, acetone, carbon tetrachloride, and chloroform. In fact, allyl bromide is used in the synthesis of other allyl compounds, to synthesize dyestuff, spice, and as a curative in the medicine industry. Allyl bromide has a very high mobility in soil. It is also used as a soil fumigant and as a contact poison. Allyl bromide induces unscheduled DNA synthesis in HeLa cells.

Scheme 1 displays synthesis of EtAIDB. 4.43 g (0.016 mol) of bis(benzimidazol-2-ylmethyl)amine (IDB) [31], with 2.32 g (0.019 mol) allyl bromide and 2.62 g (0.019 mol) anhydrous potassium carbonate in 40 mL DMF, was refluxed for 12 h. The brown aqua layer was collected. Yellow precipitate (bis(benzimidazol-2-ylmethyl)allylamine (AIDB)) was produced by addition of distilled water, washed, and recrystallized from MeOH. 3.16 g (0.01 mol) of AIDB and 0.78 g (0.02 mol) of potassium were added in THF (100 mL) and the solution was refluxed on a water bath for 4 h with stirring [32]. Then, 2.84 g (0.02 mol) of iodoethane was added to this solution. With the addition of iodoethane, the solution gradually became cream yellow. After that, the resulting solution was concentrated and cooled until a claybank-colored solid separated, then the precipitate was filtered, washed with excess water, and recrystallized from methanol to give EtAIDB. Yield 2.48 g (72.1%). Anal. Calcd for C23H27N5 (%): C, 73.23; H, 6.44; N, 20.33. Found (%): C, 73.19; H, 6.38; N, 20.27. Selected IR data (KBr ν/cm-1): 1606 ν(C=C), 1479 ν(C=N), 1288 ν(C-N). UV/Vis (DMF): λ = 278 nm. ΛM (DMF, 297 K): 10.5 S·cm2·mol−1. 1H NMR (400 MHz, d6-DMSO): δ (ppm) = 7.2–7.6 (m, 8H, –H–Ar), 5.87 (s, 1H, H–C = C), 5.1–5.3 (d, 2H, H–CH), 4.1–4.5 (m, 8H, H–CH–CH3), 3.02 (d, 2H, H–CH = CH), 1.29 (d, 6H, H–CH2–CH2).

1H-NMR spectrum of TAPA showed peaks belonging to protons of allyl groups and phenyl groups (Figure 2). The protons of methylene group belong to allyl units appeared at 2.8 ppm (H4–N–CH2) and 3.5 ppm (H1–O–CH2). The signals at 5.1 ppm belong to H-3 and H-6 and 5.65 ppm belong to H-2 and H-5 protons of allyl units. Aromatic protons of the phenylalanine were observed at 7.0–7.4 ppm. The absence of the proton signals belongs to carboxylic acid and amine groups in the 1H-NMR spectrum of TAPA confirmed the successful reaction between l-phenylalanine and allyl bromide.
