## Abstract The synthesis of benzo[a]pyrene‐6‐^13^C is described. Perinaphthane was converted to 6‐benzoyl‐carbonyl‐^13^C‐perinaphthane which was cyclized to 2,3‐dihydrobenzo[a]pyren‐6(1H)‐one‐6‐^13^C. Subsequent reduction of the ketone followed by dehydration and dehydrogenation gave benzo[a]pyren

Abstract
6‐Lithiobenzo[a]pyrene was carbonated to produce benzo[a]pyrene‐6‐carboxylic‐^14^C acid, which was in turn used in the preparation of several derivatives. Methylation to the ester was followed by LiAlH~4~ reduction to 6‐hydroxymethyl‐^14^C‐benzo[a]pyrene. An efficient oxidation using DDQ produced the corresponding aldehyde. Direct reduction of the ester using LiAlH~4~ and AlCl~3~ produced 6‐methyl‐^14^C‐benzo[a]‐pyrene.
