AbstractDeprotonation, methylation, and air oxidation of polycyclic arenes coordinated to chromium(0), (η6‐arene)Cr(CO)3, produced ring‐methylated products with high selectivity and in good yield. This procedure gave 3‐methylbenz[a]anthracene from (η6‐benz[a]anthracene)Cr(CO)3, 3‐methylphenanthrene from (η6‐phenanthrene)Cr(CO)3, 2‐acetyl‐6‐methylphenanthrene from (η6−2‐acetylphenanthrene)Cr(CO)3, and 3,7,12‐trimethylbenz[a]anthracene from (η6−7,12‐dimethylbenz[a]anthracene)Cr(CO)3.
