US 4,216,191 A · Method of preparing inorganic-alkali metal salts

Abstract

The present invention is directed to a method of preparing an inorganic-alkali metal salt of the formula: ZY wherein Z is an alkali metal selected from the group consisting of lithium and sodium, and wherein Y is an inorganic radical selected from the group consisting of SCN, CN, CNS, OCN, Br, I, Cl, NO.sub.2, NO.sub.3, ClO.sub.4, ReO.sub.4, and CF.sub.3 SO.sub.3. The method involves the reaction of a nitrogen-containing compound of the formula: QHY wherein Q is selected from the group consisting of specified nitrogen-containing groups, and wherein H is hydrogen and Y is as defined above, with an alkali metal compound of the formula: ZX wherein Z is defined above and wherein X is selected from the group consisting of hydrogen, specified nitrogen-containing radicals, and specified organic radicals. The reaction is carried out in ether solvent. In a preferred embodiment, Q is NH.sub.3 and X is hydrogen.
