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
通过新的电化学方法与超声波的使用相结合生产的超细锌粉的反应性已针对各种有机金属反应进行了评估,例如 Reformatsky 反应、Barbier 烯丙基化、炔烃还原、还原脱卤和对硝基酯裂解。结果表明,通过声电化学生产的锌粉具有高反应性。还研究了粒度效应、锌铜合金的反应性和金属废物回收程序。通过声电化学方法生产高活性锌粉似乎是有机锌化学中使用的常规方法的一种有趣的替代方法,并且在中型或大型工艺中可能尤其重要。
