## Nucleophilic aromatic substitution / Oxidative nucleophilic substitution of hydrogen The reaction of primary amines bearing tertiary alkyl groups substituted to afford N,NΠ-di(tert-alkyl)-4-nitro-2-nitroso-1,3phenylenediamines 8a,b. The addition of oxidizing agents (e.g. R-NH 2 ; R = tBu, 1-ada
Empirical solvent polarity parameters E T (30) were determined by UV/VIS spectroscopy, using Dimroth-Reichardt's betaine dye, as a function of composition, for several binary solvent mixtures [i.e. polar hydrogen bond acceptor (PHBA) solvents + chloroform or dichloromethane]. Each solvent system was
