The first monomeric monohydride derivatives of the 4f- and 5f-block metals are described; HTh(N(SiMe/sub 3/)/sub 2/)/sub 3/ and HU(N(SiMe/sub 3/)/sub 2/)/sub 3/. Reaction of chloro(tris(hexamethyldisilylamido)) thorium (IV) with i molar equiv of sodium hexamethyldisilylamide in refluxing tetrahydrofuran yields thorium hydride in pentane. The deuteride can be prepared by refluxing the starting compounds in perdeuteriotetrahydrofuran. The uranium hydride and deuteride can be prepared similarly. The reaction products were characterized by mp, ir and NMR spectra, although the hydride signal was not located in the /sup 1/HNMR spectrum of the uranium hydride. The metal bound hydrides were further characterized by their reaction chemistry.
