Photocarboxylation of 4H-cyclopenta[def]phenanthrene by carbon dioxide in the presence of N,N-dimethylaniline in dimethyl sulfoxide afforded 8,9-dihydro-4H-cyclopenta[def]phenanthrene-8- and 2-carboxylic acid, and 4H-cyclopenta[def]phenanthrene-8-carboxylic acid. These acids were derived into methyl-4H-cyclopenta[def]phenanthrenes.
4H-环戊二[def]菲在二甲基亚砜中在N,N-二甲基苯胺存在下通过二氧化碳光羧化得到8,9-二氢-4H-环戊二[def]菲-8-和2-羧酸,和4H-环戊二烯[def]菲-8-羧酸。这些酸衍生成甲基-4H-环戊二烯[def]菲。
