With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.2973-17-3,1-Allyl-1H-pyrrole-2,5-dione,as a common compound, the synthetic route is as follows.
Synthesis Example f-III-4 Synthesis of Silicone Compound: 1 = 1, m = n = 0, X1 = X3 = Substituent A-6 in the Chemical Structure 1 Drip 3.95 parts of the compound f-II: N-aryl maleimide, 10 parts of toluene, and 0.055 parts of xylene solution of 2 % by weight platinum / 1,3-divinyl-1,1,3,3-tetramethyl disiloxane complex (manufactured by Sigma-Aldrich Co.) to a solution of 3.0 parts of silicone compound: (1,1,3,3,5,5-hexamethyl trisiloxane (manufactured by Sigma-Aldrich Co) and 3.0 parts of toluene in about 60 minutes while stirring at a room temperature followed by reaction under the same condition one night. Thereafter, distill away the solvent with a reduced pressure, conduct stripping treatment for two hours with a reduced pressure of 10 mmHg at 40 C and confirm disappearance of absorption (2155 cm-1 of Si-H in infra-red absorption spectrum to obtain 4.85 parts of the target silicone compound f-M4. The infra-red absorption spectrum graph is shown as Fig. 8D., 2973-17-3
2973-17-3 1-Allyl-1H-pyrrole-2,5-dione 18098, apyrrolines compound, is more and more widely used in various fields.
