ABSTRACT:
9-Anthracenecarbaldehydes are obtained in a particularly advantageous manner by reacting the corresponding anthracene derivatives with dimethylformamide in the presence of phosphoryl chloride, hydrolyzing the resulting reaction mixture and precipitating the 9-anthracenecarbaldehyde that is formed by admixing a base.
