Popis:	Alkali-isocyanoacetates. Synthesis and Structure of [K(18-crown-6)](O2CCH2NC) The alkali isocyanoacetates M+[O2CCH2NC]− (M = Li,Na,K,Cs) (1a-d) are synthesized by reaction of ethyl isocyanoacetate with the respective alkali hydroxides in ethanol and characterized by IR, NMR (1H, 13C), and mass spectrometry (FAB). In alcoholic solution as well as in the gas phase ion pairs and higher aggregated species are observed. In contrast, [K(18-crown-6)][O2CCH2NC] (2) which is obtained from 1c and 18-crown-6, turns out to be a 1:1 electrolyte in solution (acetone); in the solid, the isocyanoacetate anion binds to K+ via the two carboxylate oxygen atoms resulting in an O8-coordinated metal atom.
