here an understanding of systems chemistry on small molecules through covalent mechanochemistry. As a proof-of-concept, the multicomponent Biginelli reaction by subcomponent synthesis was considered as a model system. Reactions were performed under solvent-free, metal-free, mechanochemical (ball milling) and ambient laboratory conditions. Br+-catalyzed oxidation of benzyl alcohols led to the product
