Oxidation of Heterocyclic Nitrogen Ylids to Nitro Heterocycles. Comparison of a Sulfilimine and a Phosphine Imine
Coburn, Michael D.
, p. 421 - 423 (2007/10/02)
Oxidation of 3-amino-4-(4-chlorophenyl)furazan (1) with peroxytrifluoroacetic acid (ptfa) gave azoxy(4-chlorophenylfurazan) (6) as the major product along with a small amount of 3-(4-chlorophenyl)-4-nitrofurazan (5).The dimethylsulfilimine 2 derived from 1 gave near quantitative yields of 5 when subjected to oxidation with either pfta or m-chloroperoxybenzoic acid (mcpba).In contrast, both the trioctylphosphine imine 3 and the triphenylphosphine imine 4 derived from 1 were oxidized by mcpba to give 6 as the exclusive product.
