Reactions of (1,3,3-Trichloro-2,2,4,4-tetramethylcyclobutyl)sulfenyl Chloride with Some S- and O-Nucleophiles


Woznicka, M; Mloston, G; Heimgartner, H (2009). Reactions of (1,3,3-Trichloro-2,2,4,4-tetramethylcyclobutyl)sulfenyl Chloride with Some S- and O-Nucleophiles. Phosphorus, Sulfur, and Silicon, 184(5):1314-1322.

Abstract

The sterically crowded 3,3-trichloro-2,2,4,4-tetramethylcyclobutanethione (2c) easily reacts with phosphorus pentachloride in CCl4 yielding the relatively stable (1,3,3-trichloro-2,2,4,4-tetramethylcyclobutyl)sulfenyl chloride (3c). The reactions of 3c with benzylsulfane (4) and thiocamphor (5) occur with elimination of HCl leading to the unsymmetrical disulfanes 6 and 9. In the case of the sulfenates 10 and 12, which are formed as intermediates in the reactions of 3c with propargyl and allyl alcohol, respectively, the subsequent [2,3]-sigmatropic rearrangement yields the corresponding sulfoxides 11 and 13.

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.
