Herein, we report a magnetically retrievable mixed-valent Fe 3 O 4 @SiO 2 /Pd 0 /Pd II NP ( 5 ) nanocomposite system for tandem Suzuki coupling/transfer hydrogenation reaction. The nanocomposite  5  was prepared first by making a layer of    \documentclass[12pt]{minimal} 				\usepackage{amsmath} 				\usepackage{wasysym}  				\usepackage{amsfonts}  				\usepackage{amssymb}  				\usepackage{amsbsy} 				\usepackage{mathrsfs} 				\usepackage{upgreek} 				\setlength{\oddsidemargin}{-69pt} 				\begin{document}$$\hbox {SiO}_{2}$$\end{document}    SiO  2on    \documentclass[12pt]{minimal} 				\usepackage{amsmath} 				\usepackage{wasysym}  				\usepackage{amsfonts}  				\usepackage{amssymb}  				\usepackage{amsbsy} 				\usepackage{mathrsfs} 				\usepackage{upgreek} 				\setlength{\oddsidemargin}{-69pt} 				\begin{document}$$\hbox {Fe}_{3}\hbox {O}_{4}\hbox {NP}$$\end{document}Fe  3    O  4   NPfollowed by deposition of    \documentclass[12pt]{minimal} 				\usepackage{amsmath} 				\usepackage{wasysym}  				\usepackage{amsfonts}  				\usepackage{amssymb}  				\usepackage{amsbsy} 				\usepackage{mathrsfs} 				\usepackage{upgreek} 				\setlength{\oddsidemargin}{-69pt} 				\begin{document}$$\hbox {Pd}^{0}$$\end{document}    Pd  0and sorption of    \documentclass[12pt]{minimal} 				\usepackage{amsmath} 				\usepackage{wasysym}  				\usepackage{amsfonts}  				\usepackage{amssymb}  				\usepackage{amsbsy} 				\usepackage{mathrsfs} 				\usepackage{upgreek} 				\setlength{\oddsidemargin}{-69pt} 				\begin{document}$$\hbox {Pd}^{\mathrm{II}}$$\end{document}    Pd  IIions successively onto the surface of Fe 3 O 4 @SiO 2 NP.

Interestingly, the mixed-valent nanocomposite Fe 3 O 4 @SiO 2 /Pd 0 /Pd II NP ( 5 ) exhibited tandem Suzuki coupling/transfer hydrogenation reaction during the reaction of aryl bromide with aryl boronic acid (90% of  C ). The nanocomposite  5  displayed much better reactivity as compared to the monovalent Fe 3 O 4 @SiO 2 /Pd 0 NP ( 3 ) (25% of  C ) and Fe 3 O 4 @SiO 2 /Pd II NP ( 4 ) (15% of  C ) nanocomposites. Further, because of the presence of magnetic    \documentclass[12pt]{minimal} 				\usepackage{amsmath} 				\usepackage{wasysym}  				\usepackage{amsfonts}  				\usepackage{amssymb}  				\usepackage{amsbsy} 				\usepackage{mathrsfs} 				\usepackage{upgreek} 				\setlength{\oddsidemargin}{-69pt} 				\begin{document}$$\hbox {Fe}_{3}\hbox {O}_{4}$$\end{document}Fe  3    O  4, the nanocomposite displayed its facile separation from the reaction mixture and reused at least for five catalytic cycles.
