Novel cellulose supported 1,2-bis(4-aminophenylthio)ethane Ni(<scp>ii</scp>) complex (Ni<sup>II</sup>(BAPTE)(NO<sub>3</sub>)<sub>2</sub>-Cell) as an efficient nanocatalyst for the synthesis of spirooxindole derivatives
Raziyeh Keshavarz, Mahnaz Farahi
Abstract
a three-component condensation of isatin, malononitrile and reactive methylene compounds. The nanocatalyst can be readily and quickly separated from the reaction mixture and can be reused for at least eight successive reaction cycles without a significant reduction in efficiency. The facile accessibility to the starting materials, use of green solvents and conducting the reactions in eco-friendly and cost-effective conditions have made this protocol a suitable method for preparing spirooxindole derivatives.
