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