{Graphical abstract}

{Abstract}Alkali metals promote a variety of organic reactions of great value for organic synthesis and industrial processes. We have found that high-surface metals' can be conveniently prepared via deposition of alkali or alkaline metals on polymeric supports from their solutions in liquid ammonia. These reagents can be conveniently stored and used in a form of stable suspensions in inert solvents. Addition of a suspension of supported alkali metal to a solution of zinc or titanium salts in THF gave highly active zinc or titanium on polymeric support. We have used these high-surface metals' for the acyloin, Dieckmann, Reformatski, Barbier and McMurry reactions, and for the preparation of organozinc and organolithium compounds.
