The bipodal compounds [(TMG2biphenN-R)CuI–NCMe](PF6) (R = Me, Ar (4-CF3Ph-)) and [(TMG2biphenN-Me)CuI–I] have been synthesized with ligands that feature a diarylmethyl- triaryl-amine framework superbasic tetramethylguanidinyl residues (TMG). cationic Cu(I) sites mediate catalytic nitrene-transfer reactions between the imidoiodinane PhI NTs (Ts tosyl) panel of styrenes in MeCN, to afford aziridines, demonstrating comparable reactivity profiles. copper reagents further explored execute C–H amination variety aliphatic aromatic hydrocarbons two distinct nitrene sources NTces (Tces 2,2,2-trichloroethylsulfamate) benzene/HFIP (10:2 v/v). Good yields obtained for sec-benzylic tert-C–H bonds various substrates, especially more electron-deficient catalyst [(TMG2biphenN–Ar)CuI–NCMe](PF6). In conjunction earlier studies, order these as function metal employed is established Cu > Fe Co ≥ Mn. However, opposed base-metal analogues, are less reactive than similar tripodal catalyst. observed fluorophilicity may provide deactivation pathway.
