The reduction of coumarin, 4-methylcoumarin, 2,2-dimethyl- 2H-chromene and 2,2,4-trimethyl-2H-chromene with sodium or lithium in liquid ammonia with the presence or without donor of protons was carried out. The formation of phenolic products was observed when a limited amount of alcohol as a proton donor was present in the reaction medium. In the experiments with excess of alcohol the products with a partially reduced benzene ring were formed
