        abstract = {A new class of dithiostannanes and dithiogermanes have been prepared from 1,1?-binaphthyl-2,2?-dithiol and 3,3?-bis(trimethylsilyl)-1,1? -binaphtho-2,2?-dithiol. While reduction of 4-butyl-4-chloro-3,5-dithia-4-stanna-cyclohepta[2,1-a;3,4- a?]dinaphthalene to the corresponding tin hydride was unsuccessful, 4-tert-butyl-3,5-dithia-4-germa-cyclohepta [2,1-a;3,4-a?]dinaphthalene and 4-tert-butyl- 2,6-bis(trimethylsilyl) -3,5-dithia-4-germa-cyclohepta[2,1-a;3,4-a?]dinaphthalene were obtained by reduction of the parent germanium chlorides with NaBH4 and LiBH4, respectively. Kinetic constants for hydrogen transfer to a primary alkyl radical were measured for both germanium hydrides. Reduction of {\ensuremath{\alpha}}-halo carbonyl compounds by these germanium hydrides occurs with moderate ee values (up to 42\%), while hydrogermylation of methyl methacrylate occurs with low selectivity ({\ensuremath{<}}3/1) for the former hydride but high selectivity ({\ensuremath{>}} 10/1) for the latter.}
