In the 1H NMR of 5, the signals of four aromatic hydrogens of benzimidazole were two doublets and two triplets at 7.34–6.12 ppm with coupling constants about 8 Hz. The signals of four aromatic hydrogens of p-cymene were observed as multiplets from 5.57 to 4.41 ppm. The hydrogens of methylene connecting the benzimidazole and phenyl moieties are diastereotopic and observed at 6.88 and 5.46 ppm as broad signals. The signals of hydrogens of other methylene carbon adjacent to nitrogen were at 5.31 ppm as a multiplet. While the signals of one hydrogen of isopropyl group in p-cymene were observed as a septet at 3.00 ppm with coupling constant of 6.8 Hz, two methyl hydrogens of isopropyl group in p-cymene were observed as overlapped with aliphatic hydrogen of cycloheptane ring. The signal of hydrogens of other methyl groups in p-cymene were observed as a singlet at 2.13 ppm. The hydrogens of methyl groups attached to phenyl ring were singlets at 2.29 (3H), 2.21 (6H), and 2.16 (6H) ppm. In the 13C NMR spectrum of 5, the signal of carbene carbon was at 187.9 ppm. The signals of ten aromatic carbons were in the range of 135.8–98.5 ppm, while the signals of four different aromatic carbons of p-cymene were observed from 86.2 to 83.8 ppm. The two methylene carbons adjacent to nitrogen atoms were observed at 52.2 and 50.3 ppm. The signals of remaining aliphatic carbons were observed in the range of 40.0–16.9 ppm.
