Synthesis, characterization and catalytic application of phenyldithiocarbazate-functionalized polystyrene supported palladium(II) complexes in the mizoroki-heck reaction

Abstract

The development of supported catalyst for chemical transformation has met the highest demand for stringent environmental due to its significance advantages in numerous applications. Due to these interest, this research has been focused on the synthesis, characterization and catalytic activity of phenyldithiocarbazate-functionalized polystyrene supported palladium(II) complexes as a potential catalyst in the Mizoroki-Heck coupling reaction. Two palladium supported catalyst were prepared using 2% cross-linked polystyrene (PS2-PDC-Pd) and 5% cross-linked polystyrene (PS5-PDC-Pd). The supported catalysts were synthesized by heating a mixture of chloromethyl polystyrene with phenylhydrazine and carbon disulfide (CS2) in the presence of potassium hydroxide (KOH) in dimethylformamide (DMF) and were treated with bis (benzonitrile) palladium(II) chloride.
