Oxidation-resistant, sterically demanding phenanthrolines as supporting ligands for copper(I) nitrene transfer catalysts

摘要

New 1,10-phenanthroline ligands have been synthesized with C_6F_5– or 2,4,6-(CF_3)_3C_6H_2– groups in the 2- and 9-positions; a cationic copper(I) complex of the latter catalyses nitrene transfer to the C–H bonds of electron-rich arenes.
