C-FORMYLATION OF α-PHENYLAMINOANTHRAQUINONES WITH FORMALDEHYDE. REACTION OF α-AMINOANTHRAQUINONES WITH FORMALDEHYDE IN SULFURIC ACID

The reaction of α-phenylaminoanthraquinones with formaldehyde in concentrated sulfuric acid leads to formylation at the para position of the phenyl group.The possibility of extending the reaction to related systems was demonstrated for the case of 6-phenylamino-N-methylanthrapyridone.It is suggested that the intermediate compounds in the C-formylation, N-methylation, and demethylation respectively of α-amino and α-methylaminoanthraquinones are 7H-7-oxoanthra-1,3-oxazinium cations.
