nitrenes for use in C-Hinsertion reactions were obtained from N-tosyloxycarbamates in the presence of an inorganic base and a rhodium(II) dimer complex catalyst. The C-H amination reaction proceeds smoothly, and the potassium tosylate that forms as a byproduct is easily removed by filtration or an aqueous workup. This new methodology allows the amination of ethereal, benzylic, tertiary, secondary

The dirhodium tetracarboxylate, Rh-2(S-TCPTAD)(4), derived from adamantylglycine, is an effective chiral catalyst for both inter- and intramolecular C-H aminations.
