Reference of 2,5-DimethoxytetrahydrofuranIn 2019 ,《Solvent Free Synthesis of N-Substituted Pyrroles Catalyzed by Calcium Nitrate》 appeared in Journal of Heterocyclic Chemistry. The author of the article were Wani, Rucha R.; Chaudhari, Hemchandra K.; Takale, Balaram S.. The article conveys some information:
Moderated and mild way for synthesizing N-substituted pyrroles I (R = 4-bromophenyl, naphth-1-yl, 2-chloropyridin-4-yl, etc.) has been demonstrated. No solvents need to be used for this reaction, and instead, reactants themselves acted as a reaction medium. In fact, the reaction is carried out using catalytic amount of Ca(NO3)2.4H2O. The reaction conditions are selective and mild that helped to tolerate a wide variety of functional groups to give the desired products I in good chem. yields. After reading the article, we found that the author used 2,5-Dimethoxytetrahydrofuran(cas: 696-59-3Reference of 2,5-Dimethoxytetrahydrofuran)
2,5-Dimethoxytetrahydrofuran(cas: 696-59-3) is a member of ether. When aromatic ethers are exposed to halogen in the presence or absence of a catalyst, they undergo halogenation, such as bromination.Reference of 2,5-Dimethoxytetrahydrofuran
