The alkylation of nitroarenes with alkanols catalysed by a phosphinesulfonate chelated ruthenium complex [Ru-1] was developed. It exhibits very different reactivity and chemoselectivity depending on acidic-basic conditions. Under either neutral or acidic conditions, nitroarenes were converted to secondary and tertiary anilines, respectively, with s...

A new class of geminally-substituted nitroso compounds, i.e. alpha-benzotriazoyl nitroso derivatives, is presented. These compounds display a rather different behavior than other related nitroso compounds bearing a geminal electron-withdrawing group. An unexpected and spontaneous oxidation to the nitro analog is observed in solution.

This study describes the syntheses and characterization of two hydrazino ureas. These fold into a six-membered ring by virtue of the infrequently observed (delta+)N-->C=O (delta-) interaction when solvated by polar protic media. The highly polar functional group resulting from this interaction is hypothesized to especially reproduce electronic but ...
