Nanoparticles of zerovalent sodium metal (5 ± 1 nm) and strontium metal (7 ± 3 nm) are realized in the liquid phase for the first time. The synthesis is performed in toluene with NaCp or SrI2 and TMEDA-stabilized [LiNaph] as reducing agent (TMEDA: N,N,N',N'tetramethylethylendiamine; [LiNaph]: lithium naphthalenide). Both nanoparticles are crystalline and highly reactive as exemplarily indicated by the formation of phase-pure alkalides.
