reactions were carried out in water at room temperature under mild and heterogeneous conditions. Moreover, temperature dependent NMR spectra were studied for 1-(2-nitrophenyl)-3,3-diethyltriazene to determine the rotational barrier energy around N(2)–N(3) bond of this molecule. Simple and clean work-up, short reaction times and good yields were the advantages of this method.

Treatment of 1-nitroso-1-phenyl- and 1-nitroso-1-(4-tolyl)-3-(4-pyridylmethyl)ureas (Ia, b) with methanol and ethanol at room temperature gave methyl and ethyl N-(4-pyridylmethyl)-carbamates (IIIa, b) in almost quantitative yields, together with benzene (IVa) and toluene (IVb), respectively. Treatment of Ia, b with benzene at 70°C gave 4-pyridylmethylamine (V) with biphenyl (VIa) and its 4-methyl derivative (VIb), respectively. Treatment of Ia, b with sodium azide in aqueous acetone at -5°C gave 1, 3-bis(4-pyridylmethyl)urea (VII) and phenylazides (VIIIa, b) in more than 90% yields.Compound Ia showed antitumor activity against rat ascites hepatoma AH13, but not against mouse lymphoid leukemia L1210. The mechanisms of these reactions and the mechanism of antitumor action of Ia are discussed

Rate constants for thermal cis-to-trans isomerization of N-(phenylazo)-substituted nitrogen ring heterocyles were determined as a function of phenyl ring substitution, cyclic amine ring size, and organic solvents. Observed first-order rate constants are found to increase with increasing electron-withdrawing character of the para substituent, with larger amine rings, and with increasing solvent polarity
