Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 20028-53-9, is researched, Molecular C7H6ClNO, about Highly Efficient and Selective Catalytic Synthesis of Quinolines Involving Transition-Metal-Doped Carbon Aerogels, the main research direction is aminobenzaldehyde Et acetoacetate Friedlaender reaction aerogel; quinole preparation; transition metal doped carbon aerogel preparation Friedlaender reaction nanocatalyst.Formula: C7H6ClNO.

Carbon aerogels doped with transition metals are found to be efficient and reusable catalysts involved in the selective synthesis of quinolines. Interestingly, we report herein the first aldol-based reactions, particularly the Friedlaender reaction, catalyzed by zero-valent metal nanoparticles, the activity of which is mainly related with the nature of the metal. Co0- and Cu0-doped aerogels resulted in the most active catalysts. Resorcinol-formaldehyde Cu-doped and steam-activated (RFCuS) aerogel represents an alternative nanocatalyst to the metal-organic framework CuBTC showing similar reactivity but superior thermal and chem. stability. The unusual reactivity observed could be explained by the in situ generation of the Co0-CoII catalytic system formed in the activation of Et acetoacetate.
