A new class of dirhodium(II) tetraamidinates derived from 2-(sulfonylimino)pyrrolidines has been prepared through ligand substitution by usingdirhodium(II) acetate, in which (3,1) geometric isomers are formed predominantly. Among these complexes, (3,1)-Rh2(Msip)4, exhibits good catalytic performance in benzylicoxidation. In the presence of (3,1)-Rh2(Msip)4 a variety of benzylic derivatives, including

tert-Butylperoxyiodane undergoes oxidation of the methylene groups α to the nitrogen atom of amides (or carbamates) yielding imides or tert-butylperoxyamide acetals, depending on the reaction conditions. A proposed mechanism involves generation of carbon-centered radicals α to the nitrogen atom.

Selective CHoxidation: A novel class of PNNP–RuII complexes is prepared and characterized. These complexes are air stable and easy to handle and show significant catalytic activity in the direct CHoxidation of aryl alkanes by using tert‐butylhydroperoxide as the reoxidant. Several functionalized ketones are prepared, which exemplifies the synthetically useful functional group tolerance of this
