A catalytic metal-free Ritter reaction to 3-substituted 3-aminooxindoles.
The first Ritter reaction of 3-substituted 3-hydroxyoxindoles with nitriles, catalyzed by HClO(4), is developed, which enables the synthesis of 3-substituted 3-aminooxindoles in good to excellent yield with rich diversity.
متن کاملIron(III) catalysed synthesis of unsymmetrical di and trisubstituted ureas--a variation of classical Ritter reaction.
An application of the classical Ritter reaction for the synthesis of unsymmetrical di and trisubstituted ureas catalyzed by FeCl(3) is described. The protocol is of significant interest in view of the easy availability of precursors, mild reaction conditions employed and interestingly its applicability for the alkylation of alcohols capable of forming stable carbocationic intermediates even to ...

This article demonstrates that the large feed-in tariffs currently guaranteed for solar electricity in Germany constitute a subsidization regime that, if extended to 2020, threatens to reach a level comparable to that of German hard coal production, a notoriously outstanding example of misguided political intervention. Yet, as a consequence of the coexistence of the German Renewable Energy Sour...
متن کاملIntervention of phenonium ion in Ritter reactions.
The transformation of phenylethyl chloride to 3,4-dihydroisoquinolines is shown to proceed via phenonium ion. The evidence comes from a study of dideuterated analogue 4, and the monomethylated and dimethylated compounds 2 and 3.
