Palladium supported on diaminoglyoxime-functionalized Fe3O4 nanoparticles as a magnetically separable nanocatalyst in Heck coupling reaction

A hybrid material of palladium supported on diaminoglyoxime-functionalized Fe3O4 was used as an effective and recyclable catalyst in Mizoroki-Heck coupling reactions. The catalyst was very effective for the Mizoroki-Heck reaction of aryl halides with styrene and conversion was in most cases excellent. The yields of the products were in the range 75-98%. The catalyst showed good stability and could be recovered and reused for six reaction cycles without significant leaching and loss its catalytic activity. Copyright (C) 2015 John Wiley & Sons, Ltd.
