 Title    Hexa(isocyanato)disilane  
 Abstract    The new compound hexa(isothiocyanato)-disilane, Si2(NCO)6, is prepared by reaction of Si2Br6 and AgNCO in toluene, and is charac­ terized by mass, vibrational as well as UV spectra.

 Title    Zur Kenntnis organischer Lewissäuren, 31 Die Lewissäureeigenschaft einiger Barbitursäurederivate * On Organic Lewis Acids, 31 Lewis Acid Properties of Some B arbiturates  
 Abstract    Arylidenbarbituric acids (4) and arylidendimethylbarbituric acids (5) are compounds w ith a polarized C = C-double bond, and hence are electrically neutral lewis acids. There­ fore they are able to add bases. The measured UV spectra show a characteristic dependence on the pH value. pK values are reported.

 Title    Darstellung und Eigenschaften von Diacetylbis(methylimin)  
 Abstract    Synthesis and Properties of Biacetylbis(methylimine) H e i n d i r k to m D i e c k * , K l a u s -D i e t e r F r a n z * u n d W e r n e r M a j u n k e Biacetylbis(methylimine) (1) is obtained by formic acid catalyzed condensation of biacetyl and methylamine. Photoelectron-and UV spectra, H NMR and 13C NMR data are compared with those of the new compound biacetylbis(isopropylimine) (2) and glyoxalbis(isopropylimine) (3).
