Abstract
A key requirement fbr the generation of active copper catalysts for olefin aziridination has been identified by examination of a copper(II) complex su pported by a new tridentate. mer-coordinating, pyridyl-appended diazacycloo ctane ligand. Combined structural, spectroscopic, and electrochemical studi es suggest that the high catalytic reactivity of complex 4 (shown) is roote d in facile access to an equatorial coordination site, occupied by a labile trifluoroacetate ligand in its X-ray crystal structure.
