Here we present the highly effective cleavage of C–C bonds in lignin modelcompounds for the production of N-substituted aromatics in up to 96% total yield, including benzonitriles and amides, via oxime formation followed by Beckmann rearrangement (BR). The amides could be further hydrolyzed to anilines (>92% yield) and carboxylic acids (>90% yield), respectively. In addition, the employment of a substrate
