Related Products of 17564-64-6, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 17564-64-6, name is 2-(Chloromethyl)isoindoline-1,3-dione belongs to indolines-derivatives compound, it is a common compound, a new synthetic route is introduced below.
To a cold (0 C.) solution of N-(chloromethyl)phthalimide (40.0 g, 205.0 mmol) in acetone (400 mL) there is added, in successive portions, potassium O-ethylxanthate (36.1 g, 225.0 mmol). The reaction mixture is stirred at 0 C. for 30 minutes and then the solvent is evaporated off. The residue thereby obtained is taken up in water. The aqueous phase is extracted with dichloromethane, whilst the organic phases are dried over MgSO4 and concentrated under reduced pressure. The residue thereby obtained is recrystallised from a mixture of ethyl acetate and petroleum ether to yield the title product in a yield of 74%. 1H NMR (delta, ppm) 7.90-7.84 (m, 2H, CH-2), 7.77-7.72 (m, 2H, CH-1), 5.33 (s, 2H, (CDCl3, 400 MHz) CH2-5), 4.68 (q, 2H, J=7.1 Hz, CH2-7), 1.46 (t, 3H, J=7.1 Hz, CH3-8).
The synthetic route of 2-(Chloromethyl)isoindoline-1,3-dione has been constantly updated, and we look forward to future research findings.
