Abstract Organoimido groups are excellent spectator ligands for high‐valent organometallic compounds due to their strong π‐donating capability. Of interest are imidochromium complexes that are used as catalysts for olefin polymerization. This microreview provides an overview of the organometallic chemistry of high‐valent imidochromium complexes. Synthetic routes to alkyl‐ and arylimido complexes of chromium in oxidation states VI−IV will be presented. The reactivity of imidochromium complexes including imido group transfer and cycloaddition will be described. The use of imidochromium complexes as catalysts for regioselective ring opening of epoxides will be discussed. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
