α-halo alkylboronic esters, acting as ambiphilic synthons, play a pivotal role versatile intermediates in fields like pharmaceutical science and organic chemistry. The sequential transformation of carbon-boron carbon-halogen bonds into broad range carbon-X allows for programmable bond formation, facilitating the incorporation multiple substituents at single position streamlining synthesis complex molecules. Nevertheless, synthetic potential these compounds is constrained by limited reaction patterns. Additionally, conventional methods often necessitate use bulk toxic solvents, exhibit sensitivity to air/moisture, rely on expensive metal catalysts, involve extended times. In this report, ball milling technique introduced that overcomes limitations, enabling external catalyst-free multicomponent coupling aryl diazonium salts, alkenes, simple halides. This approach offers general straightforward method obtaining diverse array thereby paving way extensive utilization synthons fine chemicals.
