 Title    Formation of Triradical Trications from Hexaquaternary Salts Derived from 4,4'-Bipyridine  
 Abstract    The syntheses of the hexaquaternary salts l,l'-bis-[2-(r-methyl-[4,4'-bipyridinium]-l-yl)-ethyl]-4,4'-bipyridinium hexaperchlorate and l,l'-bis-[3-(l'-methyl-[4,4'-bipyridinium]-l-yl)-propyl]-4,4'-bipyridinium hexaperchlorate are reported. The salts are reduced in aqueous solu­ tion to triradical trications at a potential (E0) of —0.24 V. We recently reported the preparation of tetra-quaternary salts derived from 4,4'-bipyridine of the

 Title    Synthese, Molekül-und Kristallstruktur von 3,5-Dimethyl-2,6-bistrimethylsilyl- l-thia-2,4,6-triaza-3,5-diborinan-wolframpentacarbonyl Synthesis, M olecular and Crystal Structure of 3,5-Dimethyl-2,6-bistrimethylsilyl- l-thia-2,4,6-triaza-3,5-diborinane-tungstenpentacarbonyl  
 Abstract    The am m onolysis o f 3,5-dim ethyl-2,6-bistrim ethylsilyl-l,4-dithia-2,6-diaza-3,5-diborinane leads to 3,5-dim ethyl-2,6-bistrim ethylsilyl-l-thia-2,4,6-triaza-3,5-diborinane, which reacts with tungstenpentacarbonyl • TH F to give the title-com pound. 'H , " B , 13C, 14N , 29Si N M R spectra, IR and MS data, and the results o f an X-ray analysis are reported.
