 Title    Reaktionen von Pyridin-Basen mit Na/K-Legierung und Diorganylaminodifluorboranen Reactions o f Pyridine-Bases with Na/K-Alloy and D iorganylam inodifluoroboranes  
 Abstract    Lutidines react with N a/K alloy and diorganylaminodifluoroboranes in «-hexane. The products formed depend upon the position o f the methyl groups. While from 3,4-lutidine (C) the bis(lutidinyl)am inoboranes 2 -5 are obtained, the 2,4-, 2,5-, and 3,5-lutidines (F, G, H) give the 11 a, 1 lb-dihydro-[l,3,2]-diazoborolo-[5,l-b;3,4-b']-dilutidines 1 1 -1 7 . 4-Picoline reacts analogously to give 10. Pyridine (A) and collidine (B) give adducts with borane. From 2,3-lutidine (D), the 1,4-dihydro-l,4-bis(fluoram inoboryl)-2,3-lutidine 8 is obtained. 'H, "B, l3C, 19F, -9Si, 15N N M R and MS data are given. For 8 and 14 the X-ray structures are reported.

 Title    Thermodynamische Untersuchungen der Systeme Pyridin/CH3SiCl3 und Pyridin/Cl3C CH3 Thermodynamic Examinations of the Systems Pyridine/CH3SiCl3 and Pyridine/C13CCH3  
 Abstract    The isobaric m elting and boiling diagrams for the systems: pyridine/m ethyltrichlorosilane and pyridine/1,1,1-trichloroethane are reproduced. The existence of the congruently melting addition com pound C H 3SiCl3-(P yridin)2 could be confirm ed. S om e m easu rem en ts o f the m olar volu m e o f m ixtures b etw een pyridine and m ethyltrichlorosilane and pyridine and 1,1,1-trichloroethane, respectively, are reported. For both system s the m olar excess v o l­ um e and for the system pyridine/m ethyltrichlorosilane the m olar excess en th alp ie have b een calculated as a function o f the m ole fractions.
