    Notes: Halogen-Carbon-Sulfur Compounds: Syntheses with 1,1,1,4,4,4-Hexafluoro-2-butene-2,3-bissulfenyl ChlorideThe bifunctional bissulfenyl chloride 3 is obtained by chlorination of the dithiete 1 or tetrathiocine 2. By excessive chlorination the saturated bissulfenyl chloride 4 is formed. 3 reacts with primary amines to yield the 1,3,2-dithiazoles 5a-e, whereas by reactions with active methylene compounds like ketones or β-dicarbonyls the compounds 7-14 are obtained with HCl elimination. 13 as well as 14 are converted into the carboxylic acid 15 from which the 1,3-dithiole 17 is obtained by decarboxylation. 3 reacts with disulfene to form tetrakis-(trifluoromethyl)tetrathiafulvalene as well as 4,4′,5,5′-tetrakis(trifluoromethyl)-2,2′-spirobi[1,3-dithiole] (18), whose crystal structure has been determined.

    Notes: Synthesis and Molecular Structure of CH3M(SiH3)3 (M=Si, Ge)A solution of 2-isotetrasilanylsodium (1a) was obtained in good yield from silane and sodium under special conditions. Methylation of 1a with methyl p1-toluenesulfonate yields 2-methylisotetrasilane (1b). The corresponding methyltrisilylgermane (2b) was synthesized via (K, Cs)Ge(SiH3)3 (2a) resulting from the reaction of cesium trichlorogermanide with KSiH3 followed by methylation. The molecular structures of 1a and 1b were determined by electron diffraction analyses.
