Abstract

A series of mono-and di-methyl substituted p-nitrosoanisoles was synthesised either by direct nitrosation of the anisoles with NO+ HSO4− or by mild oxidation (H2O2–Mo catalyst) of the appropriate amines. The nature of these compounds in solution was established by 1H and 13C NMR spectroscopy. Variable temperature 1H dynamic NMR studies provided thermodynamic data for the cases of dimer–monomer solution equilibria, and ΔG‡ data for ...
