visible light induced catalyst free convenient synthesis of Chromene nucleus and its derivatives using water ethanol mixture as a solvent
ChemInform, 2015Co-Authors: Snehlata Yadav, Madhulika Srivastava, Pratibha Rai, Jaya Singh, Kamla Prasad Tiwari, Jagdamba SinghAbstract:A highly efficient, green, eco-friendly, one pot protocol is presented for the synthesis of 2-imino-2H-Chromene-3-carbonitrile (III), 2-aminoChromene (IV), and chromeno(2,3-b)pyridines (V).

visible light induced catalyst free convenient synthesis of Chromene nucleus and its derivatives using water ethanol mixture as a solvent
New Journal of Chemistry, 2015Co-Authors: Snehlata Yadav, Madhulika Srivastava, Pratibha Rai, Jaya Singh, Kamla Prasad Tiwari, Jagdamba SinghAbstract:A highly efficient, green, eco-friendly, one pot protocol has been demonstrated for the synthesis of 2-imino-2H-Chromene-3-carbonitrile (3), 2-aminoChromene (4) and chromeno(2,3-b)pyridines (5). The synthesis of the Chromene nucleus has been carried out under visible light irradiation in a water–ethanol mixture at room temperature using salicylaldehyde and malononitrile in different proportions. The adopted method shows significant advantages such as mild and clean reaction conditions, eco-friendly procedures, absence of catalysts and a short reaction time. This protocol involves the use of CFL as the visible light source and shows high selectivity in the presence of a mixture of ethanol and water. The reaction proceeds with good to excellent yield.
