A tailor‐made copper ethylene complex was used to prepare solutions of highly reactive copper( I ) carbene complexes of the d 10 ‐ML 3 type which are active in olefin cyclopropanation and have been characterized unambigously in situ [Eq. (1)]. Electronic and structural features of this novel class of compounds were determined by NMR spectroscopy.
