## Abstract Sodium formate‐^13^C, prepared by hydrolysis of isopropyl formate, was allowed to react with N‐methylaniline hydrochloride to prepare the formylating agent N‐methylformanilide‐1‐^13^C. Formylation of benzo(a)pyrene with N‐methylformanilide‐1‐^13^C gave the 6‐^13^CHO derivative which was
## 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
