Abstract
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 2 , NO 3 , ClO 4 , ReO 4 , and CF 3 SO 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 3 and X is hydrogen.
