Vinay;Sudhamani, C. N.;Harish, K. N.. And the article was included in Letters in Organic Chemistry in 2013.SDS of cas: 51473-74-6 This article mentions the following:
Coumarin derivatives were synthesized using magnetically recoverable iron oxide nanoparticles supported amino acids as heterogeneous catalysts via one-pot multi component reaction using MW irradiation Easy recovery of the catalyst using an external magnet, efficient recycling, and reusable without significant loss of their catalytic efficiency makes the protocol greener and sustainable. In the experiment, the researchers used many compounds, for example, 7-(Diethylamino)-2-oxo-2H-chromene-3-carbonitrile (cas: 51473-74-6SDS of cas: 51473-74-6).
7-(Diethylamino)-2-oxo-2H-chromene-3-carbonitrile (cas: 51473-74-6) belongs to nitriles. Trimerization of aromatic nitriles requires harsh reaction conditions, high temperatures, long reaction times, and pressure. Nitriles are susceptible to hydrogenation over diverse metal catalysts. The reaction can afford either the primary amine (RCH2NH2) or the tertiary amine ((RCH2)3N), depending on conditions.SDS of cas: 51473-74-6
