Abstract: β;-Diketiminato Cui-lutidine complexes [RMeNN]Cu(2,4-lutidine) (R = Me (4a), iPr (4b)) were prepared in high yield from Tl[RMeNN] and [CuBr(2,4-lutidine)2]2. Both 4a and 4b reversibly dissociate lutidine base in toluene to give [RMeNN]Cu(toluene) solvento complexes. A related base-free dicopper species {[Me2NN]Cu}2 (6) bridged via η²-binding of opposing N-aryl rings could be isolated by the addition of Tl[Me2NN] to CuBr. The lutidine precursors serve as precatalysts for the aziridination of alkenes with PhI=NTs. Styrene, β;-methylstyrene, and cyclooctene gave the highest yields (59-96%) with a low olefin to PhI=NTs ratio (3:1) and 5 mol % catalyst loading. [ABSTRACT FROM AUTHOR]
