                                    General methods have been worked out for the alkylation of nitroazoles with bromoacetone, bromoacetophenone, and diazoacetone in homogeneous media and by phase-transfer catalysis.  The structures of the N-acetonylazoles were established by C-13, N-15, and N-14 high-resolution NMR spectroscopy.
