Pippal, Parveen; Singh, Prabal Pratap published an article in 2017, the title of the article was Calcium ferrite, an efficient catalyst for Knoevenagel condensation (A green approach).Quality Control of 2-((1H-Indol-3-yl)methylene)malononitrile And the article contains the following content:
Calcium ferrite NPs catalyst were used as a cheaper and highly efficient catalyst for Knoevenagel condensation of active methylene substrates with various carbonyl compounds affording condensed products in excellent yields in shorter reaction time. The developed greener protocol was very simple, involving cleaner work up and the synthesized products did not require further purification The catalyst was easily removed and reused at least for four times without any appreciable change in reactivity. 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
