A convenient, efficient, and general procedure for the synthesis of diaryl chalcogenides including sulfides, selenides and tellurides has been developed by the reaction of diazonium tetrafluoroborates and diaryl dichalcogenides on the surface of alumina under ball-milling without any solvent or metal.
Ball milling of rye bran gave rise to similar results, with the A/X ratio of the extractable AX being considerably lower (0.51). Optimization of the ball mill treatment by varying the degree of filling of the milling jar permitted us to obtain equally high WE-AX levels (>70%) in wheat and rye bran within a 24 h ball-milling period.

Ball milling is one of central techniques of mechanochemical synthesis, that is, chemical synthesis by the action of mechanical force, such as by grinding, stretching, or shearing. Mechanisms underlying chemical reactions in ball milling involve abrasion, shearing, and friction, making ball-milling chemistry one of central areas in tribochemistry.
