Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 4254-29-9, name is 2,3-Dihydro-1H-inden-2-ol. This compound has unique chemical properties. The synthetic route is as follows.
A mixture of indan-2-ol (15, 99.7 mg, 0.74 mmol, 1 eq.), pyridinium chlorochromate (241.9 mg, 1.12 mmol, 1.5 eq.) and CH2Cl2 (3 mL) was vigorously stirred for 4 h at rt. A small amount of silica was added. Et2O (5 mL) was added and the reaction mixture was filtered under pressure. The residue was washed with Et2O. The filtrate was concentrated in vacuo. The crude product was purified by fc (d = 2 cm, l = 11 cm, v = 10 mL, cyclohexane:EtOAc 8:2, Rf = 0.11), yellow oil, yield 67.1 mg (68 %). C9H8O (132.2 g/mol). FT-IR (neat): nu (cm-1) = 2924 (C-H), 1743 (C=O), 740 and 648 (1,2-disubst. arom.). 1H NMR (400 MHz, CDCl3): delta (ppm) = 3.57 (s, 4H, 1-CH2, 3-CH2), 7.26 – 7.34 (m, 4H, Ar-H). 13C NMR (101 MHz, CD3OD): delta (ppm) = 44.2 (2C, C-1, C-3), 125.1 (2C, Cind), 127.5 (2C, Cind), 137.9 (2C, Cqind), 215.3 (1C, C=O). Exact Mass (APCI): m/z = 133.0654 (calcd. 133.0648 for C9H9O [M+H+]). Purity (HPLC, method 2) = 98.8 % (tR = 14.29 min).
According to the analysis of related databases, 4254-29-9, the application of this compound in the production field has become more and more popular.
