On August 31, 2004, Narsaiah, A. Venkat; Basak, A. K.; Visali, B.; Nagaiah, K. published an article.Quality Control of 2-((1H-Indol-3-yl)methylene)malononitrile The title of the article was An eco-friendly synthesis of electrophilic alkenes catalyzed by dimethylaminopyridine under solvent-free conditions. And the article contained the following:
Electrophilic olefins were synthesized in solvent-free condition using DMAP (10%mol) as catalyst in excellent yield and E-geometry. The various aldehydes which are aliphatic, aromatic, and heterocyclics under-went smoothly for Knoevenagel condensation with different active methylene compounds The experimental process involved the reaction of 2-((1H-Indol-3-yl)methylene)malononitrile(cas: 75629-62-8).Quality Control of 2-((1H-Indol-3-yl)methylene)malononitrile
