New applications of hetaryl thioketones for the synthesis of hetaryl-substituted ethenes via ‘two-fold extrusion reaction‘


Mloston, Grzegorz; Urbaniak, Katarzyna; Pawlak, Aneta; Heimgartner, Heinz (2016). New applications of hetaryl thioketones for the synthesis of hetaryl-substituted ethenes via ‘two-fold extrusion reaction‘. Heterocycles, 93(1):127-139.

Abstract

A series of aryl/hetaryl thioketones was applied for the reactions with aryl/hetaryldiazomethanes yielding, after elimination of N2, the corresponding thiiranes. The relatively unstable dihetaryldiazomethanes were generated in situ from the corresponding hydrazones by oxidation with DMSO. The obtained thiiranes were converted into tetraaryl/hetaryl-substituted ethenes in good yields by desulfurization performed with tris(diethylamino)phosphine ((Et2N)3P).

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.
