Silica-immobilized piperazine: A sustainable organocatalyst for aldol and Knoevenagel reactions was written by Shanmuganathan, Saravanakumar;Greiner, Lasse;Dominguez de Maria, Pablo. And the article was included in Tetrahedron Letters in 2010.Recommanded Product: 1-Propylpiperazine This article mentions the following:
Silica-supported piperazine was found to be an efficient catalyst for aldol reactions of aromatic aldehydes and ketones with straightforward product isolation and catalyst reuse. Furthermore, the catalyst is active in Knoevenagel-type reactions to afford coumarin derivatives, using 2-methyltetrahydrofuran (2-MeTHF) as a novel bio-based solvent. In the experiment, the researchers used many compounds, for example, 1-Propylpiperazine (cas: 21867-64-1Recommanded Product: 1-Propylpiperazine).
1-Propylpiperazine (cas: 21867-64-1) belongs to piperazine derivatives. Piperazine was first introduced as an anthelmintic in 1953. Piperazine compounds mediate their anthelmintic action by generally paralyzing parasites, allowing the host body to easily remove or expel the invading organism. Intermediate for a wide range of pharmaceuticals, polymers, dyes, corrosion inhibitors, rubber accelerators and surfactants.Recommanded Product: 1-Propylpiperazine
