Modular construction of polyfunctional arenes from abundant feedstocks stands as an unremitting pursue in synthetic chemistry, accelerating the discovery of drugs and materials. Herein, using the multiple C-H activation strategy with versatile imidate esters, the expedient delivery of molecular libraries of densely functionalized sulfur-containing arenes was achieved, which enabled the concise construction of biologically active molecules, such as Bipenamol.

An efficient aerobic chemoselective oxidation of thiols to disulfides has been achieved under ball-milling over neutral aluminium oxide (grinding auxiliary) in the absence of any catalyst, co-oxidant, solvent, or base. A wide variety of functionalized diaryl, diheteroaryl and dialkyl disulfides have been obtained in high yields. The Royal Society of Chemistry 2013.
Development of a tandem base-catalyzed, triphenylphosphine-mediated disulfide reduction-Michael addition
Bartolozzi, Alessandra,Foudoulakis, Hope M.,Cole, Bridget M.
experimental part, p. 2023 - 2032 (2009/04/03)
A tandem disulfide reduction-Michael addition was developed using both free and polymer-bound triphenylphosphine as the reducing agent. The procedure was applied to intermolecular systems for the synthesis of arylsulfanyl- and alkylsulfanyl-substi-tuted p

Asymmetric copper complexes of stable mono-tert-butyl monobenzyl dithioether N2S2 ligands
Nation, David A.,Taylor, Max R.,Wainwright, Kevin P.
, p. 3001 - 3009 (2007/10/03)
Attempts to form copper complexes of new N2S2 compounds, in which one sulfur donor is a thiolate and the other a thioether, have been made by protecting the potential thiolate through tert-butylation and benzylating the other. Wherea
Chemistry of Sulfenic Acids. 7. Reason for the High Reactivity of Sulfenic Acids. Stabilization by Intramolecular Hydrogen Bonding and Electronegativity Effects
Davis, Franklin A.,Jenkins, Linda A.,Billmers, Robert L.
, p. 1033 - 1040 (2007/10/02)
It is proposed that the reason sulfenic acids (RSOH) are so reactive and usually not isolated or even detected is that they form thiosulfinates (RS(O)SR) so readily.This is a consequence of the sulfenic acid hydrogen-bonded dimer, 1, which lowers the energy of activation for thiosulfinate formation.The stability of the few sulfenic acids that have been isolated can be explained in terms of steric, electronic, and intramolecular hydrogen-bonding effects which prevent dimer formation.The importance of these effects on the stability of simple unstable sulfenic acids was demonstrated by flash vacuum pyrolysis (FVP) and the thiosulfinate/vinyl sulfoxide ratio.A novel, high yield, rearrangement of sulfenic acid 19f to 1,3-benzothiazine 26 was observed.
