Desulfonylative Arylation of Redox-Active Alkyl Sulfones with Aryl Bromides [PDF]

, 2019
Herein we describe the development of the first reductive cross-electrophile coupling between alkyl sulfones and aryl bromides. The use of alkyl sulfones as coupling partners offers strategic advantages over other alkyl electrophiles used in reductive ...

Preparation of Alkyl Alkynyl Sulfones and Cyclic Vinyl Sulfones from Alkynyl(aryl)iodonium Salts [PDF]

, 2016
The reaction of alkyl sulfinates with alkynyl(aryl)iodonium salts provides a facile access in to otherwise difficult to obtain alkyl alkynyl sulfones and cyclic vinyl sulfones via 1,2-rearrangement or 1,5-CH insertion respectively.

Microbial Degradation of the Sulfonate of Dodecyl Benzene Sulfonate [PDF]

Applied Microbiology, 1965
It has been observed that the sulfonate portion of alkyl benzene sulfonate (ABS) will undergo microbial attack in certain pure and mixed cultures if an energy source, such as glucose, is available. The evidence for this is provided by the stoichiometric relationship between the reduction of ABS concentration and the appearance of inorganic sulfur ...
