In this article, we have studied the generation of a bissulfinylmethyl radical from the corresponding TEMPO and phenylselenyl bissulfoxide precursors. No univocal formation of the bissulfinylmethyl radical has been observed. Instead, complex mixtures have been obtained in thermal or photochemical conditions, showing prominent C-S homolytic bond cleavage.

Enantiomerically pure (Z)-β-sulfinyl allylic alcohols of either handedness can be readily prepared from (Z)-β-sulfinyl enones using NaBH4 or DIBAL reductants in the presence of LaCl3 as a chelating agent. A chiral sulfoxide auxiliary induces the remote 1,2-asymmetric reduction (1,4-induction) to afford various chiral allylic alcohols in high yields with excellent stereoselectivities (up to 100% de).
C2-symmetric bissulfoxides as organocatalysts in the allylation of benzoyl hydrazones: Spacer and concentration effects
Fernandez, Inmaculada,Valdivia, Victoria,Leal, Manuel Pernia,Khiar, Noureddine
, p. 2215 - 2218 (2008/02/05)
A comparative study on the allylation of a benzoyl hydrazone with allyl trichlorosilane using monosulfoxides, methylene-bridged (C2-symmetric bissulfoxides, and ethylene-bridged C2-symmetric bissulfoxides shows that the enantioselect

, p. 2449 - 2452 (2007/10/03)
An optimized procedure for the preparation of (SS,S S)-bis(p-tolylsulfinyl)methane (4) is reported. Condensation of the lithium salt of 4 onto cinnamaldehyde furnished bis-sulfoxide dienyl derivative 5, a remarkable 1,4-Michael accep
Geminal bis(sulfoximine)s: Synthesis and applications in asymmetric catalysis
Reggelin,Weinberger,Spohr
, p. 1295 - 1306 (2007/10/03)
A number of C2-symmetrical geminal bis-(sulfoximine)s have been prepared for the first time and used as ligands in boron-mediated reductions of acetophenone and copper complex-catalyzed 1,4-additions of diethylzinc to 2-cyclohexenone. The coppe
Efficient preparation of enantiomerically pure (E)-γ-hydroxy-α,β- unsaturated p-tolylsulfoxides using lipase-mediated acylations
Guerrero De La Rosa, Victor,Ordonez, Mario,Llera, Jose Manuel
, p. 2991 - 3001 (2007/10/03)
(E)-γ-Hydroxy-α,β-unsaturated p-tolylsulfoxides 1 have been efficiently resolved via irreversible enzymatic acylation with lipase PS (Pseudonomas cepacia) and vinyl acetate. (C) 2000 Elsevier Science Ltd.
