A New Synthesis of Alkyl-N,N-dinitramines by Direct Nitration of Isocyanates

Abstract A facile conversion of aliphatic isocyanates to N,N-dinitramines has been developed. An aliphatic isocyanate is treated with a mixture of nitronium fluoroborate and nitric acid in acetonitrile giving fair yields and simplifing the existing synthesis.

Expedient Synthesis of t-Butyl Azide

Abstract A simple, economical synthesis of bulk (1 to 10,000 moles) quantities of t-butyl azide is described, utilizing only t-butyl alcohol, water, sodium azide, and sulfuric acid.
