WebA recent method used the Reimer-Tiemann (R-T) reaction to produce formamides from secondary amines (Scheme 7) [31]. Alkyl, cyclic, and N-methylaniline derivatives all produced formamides in good to excellent yields, but the best yields were obtained with cyclic amines. A mechanistic pathway consistent with the R-T reaction was proposed (Scheme 8).
