Abstract The reactivity of ultrafine zinc powders, produced by a new electrochemical method coupled to the use of ultrasound, has been evaluated for various organometallic reactions such as the Reformatsky reaction, Barbier allylation, alkyne reduction, reductive dehalogenation and p ‐nitroester cleavage. The results show that zinc powders produced by sonoelectrochemistry are highly reactive. Particle‐size effects, reactivity of zinc‐copper alloys and metal‐waste recycling procedures have also been studied. The production of highly reactive zinc powder by sonoelectrochemical methods appears to be an interesting alternative to conventional methods used in organozinc chemistry and may be especially important in medium‐ or large‐scale processes.
