“High-surface alkali metals” can be conveniently prepared via deposition of corresponding metals on various supports such as sodium chloride, polyethylene, polypropylene and cross-linked polystyrene from their solutions in liquid ammonia. Alkali metals deposited on polymeric supports can be stored in form of stable suspensions in inert solvents and used for the acyloin and Dieckmann condensations and
“高表面碱金属”可通过将相应的金属从其在液氨中的溶液沉积在各种载体(例如氯化钠,聚乙烯,聚丙烯和交联的聚苯乙烯)上而方便地制备。沉积在聚合物载体上的碱金属可以在惰性溶剂中以稳定的悬浮液形式存储,并用于酰基环和Dieckmann缩合反应以及有机锂的制备。将负载的碱金属的悬浮液添加到氯化锌溶液中,可以在聚合物载体上得到活性锌,可以将其用于Reformatski和Barbier反应。
