Phase-Transfer Catalytic (PTC) Chlorination of Allylic Sulphones
Jonczyk, A.,Radwan-Pytlewski, T.
, p. 1422 - 1427 (2007/10/03)
Phase-transfer catalytic reactions of allylic sulphones with hexachloroethane or carbon tetrachloride afford mono- or dichlorinated products, with high yields. - Key words: phase transfer catalysis (PTC); allylic sulphones; halogenophilic reaction
Steric and electronic effects on the conformations and singlet oxygen ene regiochemistries of substituted tetramethylethylenes. The origin of the geminal effect
Clennan, Edward L.,Chen, Xiangning,Koola, Jaya J.
, p. 5193 - 5199 (2007/10/02)
The reactions of singlet oxygen with 22 allylically substituted tetramethylethylenes have been studied. Steric and electronic effects on the regiochemistries of the ene reactions have been discovered. Large groups and electron-rich groups increase geminal hydrogen abstraction. Molecular mechanics calculations have been conducted and reveal that the site of hydrogen abstraction is correctly predicted by the rotational barriers of the methyl groups.
Carbon Dioxide-Promoted Telomerization of 1,2- and 1,3-Dienes with Benzenesulfinate Catalyzed by Palladium(0)
Inoue, Yoshio,Hashimoto, Harukichi
, p. 3705 - 3708 (2007/10/02)
The telomerization of 1,2- and 1,3-dienes with benzenesulfinate dihydrate catalyzed by palladium(0) has been promoted by the presence of carbon dioxide
Stereochemistry of Addition of Organocopper Reagents and of the Hydride Ion to 1-(Arylsulfonyl)bicyclobutanes
Gaoni, Yehiel,Tomazic, Alenka,Potgieter, Eleonora
, p. 2943 - 2947 (2007/10/02)
Addition of methylmagnesium iodide/cuprous iodide or of lithium dimethylcuprate to 2-exo- and 2-endo-methyl-1-(phenylsulfonyl)bicyclobutane and determination of the relative geometry of the methyls in the 2,3-dimethylcyclobutanes obtained allowed u
Selective Functionalisation of 1,3-Dienes via Organosulphur Intermediates
Golding, Bernard T.,Pombo-Villar, Esteban,Samuel, Christopher J.
, p. 1444 - 1445 (2007/10/02)
The 1,2-adducts from 1,3-dienes and sulphenyl chlorides are shown to be useful intermediates by their conversions into a variety of functionalised alkenes.
