Catalytic ring‐opening of bio‐sourced non‐strained lactones with aromatic amines can offer a straightforward, 100 % atom‐economical, and sustainable pathway towards relevant N‐aryl amide scaffolds. Herein, the first general, metal‐free, and highly efficient N‐aryl amide formation is reported from poorly reactive aromatic amines and non‐strained lactones under mild operating conditions using an organic
