Copper with bridging hydrogen

Metal nitrene complexes were used in a number of C-H amination reactions (recent reviews [358, 359]). Copper ketiminate complexes react with azides to nitrene complexes, which were isolated [360]. (p-Ketiminate)copper(I) complex 262 (2.5 mol%) serves therefore as an efficient catalyst for the intermolecular C-H amination of alkylarenes, cycloalkanes, or benzaldehydes 260 using adamantyl azide 261 as the nitrogen source ig. 68) [361]. The corresponding adamantyl amines or amides 263 were isolated in 80-93% yield. Copper complex 262 forms initially a dinuclear bridged complex with 261. From this a copper nitrene complex is generated by elimination of nitrogen, which mediates the hydrogen abstraction from 260. [Pg.399]
