Preparation and Characterization of Some Isoelectronic Boron-Nitrogen Analogs of Substituted Uracil [1]

Abstract

Several 1,3,5-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 fourcoordinate boron.
