Electrochemically induced Hofmann rearrangement under new solvent systems containing a variety of alcohols was developed. Since the reaction proceeds under mild conditions (neutral), a variety of carbamates possessing various alkoxy moieties could be easi

Intermolecular aromatic C(sp2)-H amination promoted by neutral rhodium nitrenoids has been developed. The reactions proceeded with various oxygen-substituted arenes (1.5 equiv.) in a chemo- and regioselective manner. The aromatic C(sp2)-H amination took place at the para position of the oxygen substituent in the presence of benzylic C(sp3)-H bonds and/or C(sp3)-H bonds α to ethereal oxygen.

A diverse library of twenty-five 4-mono- and disubstituted semicarbazides was prepared in a one-pot two-step approach. The method includes formation of a carbamate from bis(2,2,2-trifluoroethyl)carbonate or 2,2,2-trifluoroethylchloroformate and a primary or secondary amine and subsequent interaction of the carbamate with hydrazine to result in a semicarbazide. The approach allowed to obtain 4-substituted semicarbazides on a large scale in good yield and high purity. This journal is
