Sonoelectroreduction of Metallic Salts: A New Method for the Production of Reactive Metallic Powders for Organometallic Reactions and Its Application in Organozinc Chemistry
The reactivity of ultrafine zinc powders, produced by a new electrochemical method coupled to the use of ultrasound, has been evaluated for various organometallicreactions 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
