Homogeneous catalysts display good activity, but are non-recyclable in catalysis. Meanwhile, heterogeneous catalysts can be easily reused. Homogeneous rhodium is the least abundant metal (~1% annual productivity versus gold), however, its use is essential (i.e. catalytic converters and electronics). However, the cost of Rh has increased over 500% in the last five years. Considering the advantages of heterogeneous, we present herein the synthesis and characterization of a novel self-supported dirhodium(II) catalyst, which blends stability with high catalytic activity for nitrene transfer towards the syntheses of biologically important moieties.

Self-supported dirhodium(II) heterogeneous catalyst: An efficient nitrene transfer
