Towards New Imidazole-2-Thione-Based Organocatalysts; Sulfur Transfer Vs. Deoxygenation in the Reaction of Imidazole N-Oxides and Cycloaliphatic Thioketones - Zurich Open Repository and Archive


Rygielska-Tokarska, Dorota; Jasinski, Marcin; Mloston, Grzegorz; Heimgartner, Heinz (2013). Towards New Imidazole-2-Thione-Based Organocatalysts; Sulfur Transfer Vs. Deoxygenation in the Reaction of Imidazole N-Oxides and Cycloaliphatic Thioketones. Phosphorus, Sulfur and Silicon and the Related Elements, 188:469-472.

Abstract

Sulfuration or deoxygenation? Competitive transformations of the title imidazole N-oxides into respective masked thiourea analogues or into the parent heterocycle in the reaction with 2,2,4,4-tetramethylcyclobutane-1,3-dithione are presented. The influence of an electron-withdrawing substituents in combination with the steric hindrance of neighbouring groups onto reaction outcome is discussed.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
