An elementary termolecular reaction involves the simultaneous collision of three atoms, 37441-50-2, molecules, or ions. Here is a downstream synthesis route of the compound 37441-50-2, name is :1,2-Thiazinane 1,1-dioxide
To a mixture of 2,4-difluorobenzonitrile (10.0 g, 72 mmol) and 1,1-dioxo-1lambda6-[1,2]thiazin-2-ane (8.84 g, 65.4 mmol) in 1:1 tetrahydrofuran/dimethylformamide (40 mL) was added potassium carbonate (9.0 g, 65.4 mmol). The mixture was stirred at 90 C. for 18 h then filtered and concentrated. The residue was purified by flash chromatography (SiO2) eluting with 10%-50% ethyl acetate/hexanes followed by recrystallization from hot ethyl acetate/hexane to give the title compound as white needles (0.537 g, 3% yield). 1H NMR (500 MHz, CD3OD) delta ppm: 7.70 (1H, dd, J=8.8, 5.8 Hz), 7.30 (1H, dd, J=8.8, 2.4 Hz), 7.15-7.12 (1H, m), 3.27 (2H, t, J=5.3 Hz), 3.33 (2H, t, J=6.1 Hz), 2.40-2.35 (2H, m), 2.05-2.01 (2H, m). LCMS (M+H) calcd for C11H16N2OF: 255.06; found: 255.19., 37441-50-2
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 37441-50-2.
