An Efficient Protocol for Synthesis of 2-amino-3cyanopyridine Derivatives using Nano-modified SBA-15

Condensation reaction of chalcones with malononitrile and ammonium acetate in the presence of the green nano-modified SBA-15 affords the corresponding 2-amino-3-cyanopyridine derivatives in excellent yield. This approaches claimed to be an environment friendly protocol as it afforded some advantages such as excellent yields and cleaner reaction.

Brønsted Acidic Phosphonium Based Ionic Liquid Functionalized SBA-15 [HO3S-PhospIL@SBA-15]: Green, Recyclable, and Efficient Catalyst for the Synthesis of Pyrano[3,2-c]Chromenone Derivatives

The surface of SBA-15 was modified by diphenylphosphine; then, it was treated with butane sultone and sulfuric acid to obtain Brønsted acid HO3S-phosphonium based ionic liquid functionalized SBA-15 with HSO4- as a counteranion. It efficiently catalyzed synthesis of pyrano[3,2-c]chromenone derivatives through the reaction of 4-hydroxycoumarin and chalcones at...

SBA-15-supported-dithizone-copper(I): An efficient heterogeneous catalyst for synthesis of 1,4-disubstituted 1,2,3-triazoles in water

In this work, the SBA-15-supported dithizone-copper(I) [SBA-15-dtz–Cu(I)] complex as a new heterogeneous catalyst is prepared for the first time. The catalyst prepared is characterized by the FT-IR spectroscopy, SEM, and ICP techniques. This reusable heterogeneous catalyst can be used in the click reactions for the green and facile synthesis of 1,4-disubstituted 1,2,3-triazolesvia a on...
