α- and β-[Fe2(μ-StBu)2(StBu)4]2-: Coexistence of two bond-stretch isomers of a classical bitetrahedral metal chalcogenolate compound was written by Hammann, Bernd;Chen, Changneng;Floerke, Ulrich;Hauptmann, Ralf;Bill, Eckhard;Sinnecker, Sebastian;Henkel, Gerald. And the article was included in Angewandte Chemie, International Edition in 2006.Reference of 29364-29-2 This article mentions the following:
[Fe2(StBu)6]2- shows a new form of isomerism. Besides the isomer of classical structure for [Fe2(μ-StBu)2(StBu)4](NMe4)2 (1a) there is also a variant (1b) in which the central Fe2S2 rhomb is inverted and the Fe-S bonds are distinctly shorter. 1B can be regarded as a transition state during the inversion of the bridging S atoms of 1a that is stabilized by significant π interactions. In the experiment, the researchers used many compounds, for example, Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2Reference of 29364-29-2).
Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2) belongs to alcohols. The oxygen atom of the strongly polarized O―H bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.Reference of 29364-29-2
