The concept of green chemistry began in the USA in the 1990s. Since the publication of the
12 principles of this concept, many reactions in organic chemistry have been developed …

The scale-up of the Knoevenagel-condensation between vanillin and barbituric acid carried
out in planetary ball mills is investigated from an engineering perspective. Generally, the …

5-Hydroxymethylfurfural (HMF) is a well-known platform chemical derivative from biomass.
Herein, we described the application of boric acid deposited on hydrotalcite as a catalyst in …

This review describes the synthetic procedures for the preparation of
arylideneacetophenones, arylidenecycloalkanones, 2-arylidene-1-indanones, 2-arylidene-1 …

This work describes a first-ever use of Wet copper-slag for efficient Knoevenagel
condensation. Copper-slag is produced as a byproduct of the copper refining and smelting …

In this article we report a sustainable and rapid-room temperature synthesis of α-
cyanoacrylonitriles, α-cyanoacrylates, and 4H-pyrans via the condensation of active …

The Knoevenagel condensation between active methylene compounds and aromatic
carobonyl compounds has been developed using quinine as an organocatalyst to afford …

A piperidinium borate, an organic conjugate base as a catalyst under mild conditions,
effectively promotes Knoevenagel condensation between aromatic, heterocyclic, α, β …

Ionic liquid coated sulfonic acid functionalized amorphous carbon/silica composites derived
from a starch–glucose mixture were developed and their catalytic activities were evaluated …

The aim of this study was to synthesize different multifunctional materials containing 5-(4-
carboxyphenyl)-5, 10, 15-tris (4-phenoxyphenyl)-porphyrin and iron oxide magnetic …
