This critical review summarizes, mainly from author's own laboratory, the strategy to incorporate the advantageous attributes of both, the homogeneous and heterogeneous catalysts by using nano-catalysts, especially those that are magnetically retrievable. This may be useful for synthetic and medicinal chemists interested in green synthesis of precursors and intermediates that may be devoid of metal residues.
