Investigation of the alkylation of nitroazoles with ?-haloketones by13C,15N, and14N NMR
摘要:
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.
