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.
Diverse opportunities: A Rhodium(III)‐catalyzed ortho‐selective olefination of arenes using a novel triazene as a directing group is reported. This method exhibits substantial post‐functionalization synthetic versatility, overcoming a vital limitation in CHactivation/functionalization products: restricted structural diversity.
