 Title    Kristall-und Molekülstruktur von N,N'-Bis(l,3-dimethylbenzo[b]-l,3?2-diazaboroIidin-2-yl)carbodiimid Crystal and Molecular Structure of N,N'-Bis(l,3-dimethylbenzo[b]-l,3,2-diazaborolidin-2-yl)carbodiimide  
 Abstract    Crystals of the title compound (2) are monoclinic with a = 905.5(3), b = 593.6(2). c — 3243.5(8) pm, ß = 95.63(2)°, Z = 4, space group P2 x ln. The molecule 2 neither has a C 2 -symmet-rical allene-type nor a D 2d -symmetrical cumulene-type structure, but it has a non-linear B-N = C=N —B arrangement and is nearly planar. The central N = C=N angle has a value of 171.9(3)°, the B —N = C angles are 145.9(2)° and 163.1(3)°.

 Title    Preparation and Characterization of Some Isoelectronic Boron-Nitrogen Analogs of Substituted Uracil [1]  
 Abstract    Several l,3,5-triaza-2-boracyclohexa-4,6-diones, which are isoelectronic analogs of substituted uracil, have been prepared by condensation reactions of boranes with biurets. They include species containing a NH or BH unit as potentially reactive sites. The latter are extremely sensitive to hydrolysis but are readily handled as the 2-methylaminoethanol derivative containing four-coordinate boron.
