The invention relates to compounds of a new type which have a stabilizing effect and in particular provide stabilization with respect to oxidative thermal and/or actinic decomposition of or damage to organic materials. The compounds are represented by general formula I specified below. The invention further relates to a method for producing such compounds, to compositions containing said compound, to a method for stabilizing organic compounds by means of the stabilizing compounds, and to the use of the stabilizing compounds to stabilize organic materials.

The thiol-ene coupling (TEC) reaction has attracted a lot of scientific attention during the last years, particularly in the fields of polymers, materials and more recently in drug design. The combination of organocatalysis and photocatalysis has enabled the development of an efficient synergistic protocol for the addition of various thiols to a plethora of olefins. Utilizing phenylglyoxylic acid as the catalyst-initiator and common household bulbs as the light source, we report an organocatalytic photoinitiated TEC reaction showing exceptional tolerance in the presence of various functionalities, untangling previously unsolved problems.

The epoxy-Ramberg-Baecklund reaction (ERBR): A sulfone-based method for the synthesis of allylic alcohols
Evans, Paul,Johnson, Paul,Taylor, Richard J. K.
, p. 1740 - 1754 (2007/10/03)
The epoxy-Ramberg-Baecklund reaction (ERBR) is outlined, in which α,β-epoxy sulfones are converted into a range of mono-, di- and tri-substituted allylic alcohols, on treatment with base. Modification of this method enabled the preparation of enantio-enriched allylic alcohols following the diastereoselective epoxidation of enantio-enriched vinyl sulfones that were accessed efficiently from the chiral pool. The scope, optimisation and limitations of the ERBR as a method for the preparation of allylic alcohols are discussed. Wiley-VCH Verlag GmbH & Co. KGaA, 2006.
NOUVEAUX DECONTAMINANTES. DESTRUCTION OXYDATIVE D'UN SILIMI DE L'YPERITE: LE PHENYL-2 CHLORO-2' DIETHYLSULFURE PAR LE MONOPERSULFATE DE POTASSIUM

The reaction of potassium monopersulfate (CUROX or OXONE) with 2-phenyl 2'-chloro diethylsulfide PhCH2CH2SCH2CH2Cl goes to completion in a very short time.The intermediate chlorinated sulfone PhCH2CH2SO2CH2CH2Cl leads to the phenethylvinylsulfone PhCH2CH2SO2CH=CH2 by HCl elimination. Key words: decontamination; potassium monopersulfate; yperite.
NOUVEAUX DECONTAMINANTS. DESTRUCTION DE TOXIQUES ORGANOPHOSPHORES OU SOUFRES PAR DES PERACIDES MONO-, BI- ET TRICYCLIQUES SATURES

, p. 249 - 256 (2007/10/02)
New peroxycarboxylic and peroxyacetic acids have been tested for the destruction of some organophosphorus compounds and mustards.The peroxyacids used have monocyclic, bicyclic or tricyclic structures.These are very reactive against paraoxon or HD and the addition of certain surfactants enhances the reaction rate.Very short half-live times are obtained with these compounds.
NOUVEAUX DECONTAMINANTS. DESTRUCTION DU PARAOXON ET D'UN SIMILI DE L'YPERITE PAR QUELQUES ACIDES HYDROXAMIQUES
Lion, C.,Hedayatullah, M.,Bauer, P.,Boukou-Poba, J. P.,Charvy, C.,et al.
, p. 617 - 621 (2007/10/02)
A new series of hydroxamic acids 1-4 has been used in the destruction of paraoxon (O,O-diethyl O-paranitrophenylphosphate) and a mustard-related compound (2-chloro 2'-phenyl diethylsulfide).These hydroxamic acids are N-alkyl substituted isonicotinhydroxamic acid 1, and quinolone derivatives 2 norbornyl- and adamantylhydroxamic acids 3 and 4.The latter are very reactive and the addition of certain surfactants enhances the rate of the reaction.Very short half-lives are obtained with these compounds.
