Secondary amines are formylated by dimethylformamide dimethylacetal, contradicting recent reports on the ethylation of secondary amines by this reagent. This explains why a single derivative is obtained regardless of the alkyl acetal that is used. These formyl derivatives, also formed by reaction with...
