| Outline of Final Research Achievements |
We discovered that only concentrated sulfuric acid was able to completely disperse the g-C3N4, leading to the production of a novel, highly porous carbon nitride material (labeled as nanoporous carbon nitride, nanoC3N4) with a high surface area. We succeeded in the Knoevel reactions of cyanoacetate with aldehydes in water solvent in high efficiency by using nanoC3H4 as a solid base catalyst. NanoC3H4 is insoluble in water, thus isolable by simple filtration after the reaction and reusable. Thus we developed a new methodology for the Knoevel reactions performed in water rather than in organic media. This is a great advantage of performing organic synthesis in aqueous media in light of "green chemical processes" for organic transformations.
