Poly (vinylpyrrolidone)-Grafted Silica as a Polymeric Cosolvent Catalyst for Organic Transformations in Organic and Aqueous Media
Poly (vinylpyrrolidone)-grafted silica as an organic-inorganic hybrid material was used as an effective heterogeneous polymeric cosolvent catalyst in organic reactions. This modified silica catalyzed nucleophilic displacement of alkyl halides for easy preparation of alkyl thiocyanates, alkyl cyanides, alkyl azides and alkyl aryl ethers. Furthermore, the catalyst was applied for the conversion o...
متن کاملL-proline: An efficient catalyst for the synthesis of quinoline derivatives in aqueous media
An efficient and direct procedure for the synthesis of benzo[h]-indeno[1,2-b]-quinoline derivatives has been described. The procedure employs a three-component condensation reaction in one-pot using 2H-indene-1, 3-dione, naphthalen-1-amine,and aldehydes in the presence of catalytic amount of L-prolinein aqueous media.
