Efficient synthesis of vinyl and alkyl sulfides via hydrothiolation of alkynes and electron-deficient olefins using soluble and heterogenized gold complexes catalysts
Corma, Avelino,González-Arellano, Camino,Iglesias, Marta,Sánchez, Félix
scheme or table, p. 49 - 54 (2010/08/06)
Soluble and heterogenized gold complexes catalyze the hydrothiolation of alkynes and electron-deficient olefins in high yields and with high anti-Markovnikov selectivity. Moreover heterogenized catalysts could be recycled in several successive runs withou
From vinyl sulfides, sulfoxides and sulfones to vinyl zirconocene derivatives
Farhat, Shahera,Zouev, Irena,Marek, Ilan
, p. 1329 - 1337 (2007/10/03)
An easy and straightforward new method for the preparation of sp 2 zirconocene derivatives from a wide range of heterosubstituted alkenes such as vinyl sulfides, sulfoxides and sulfones is described. In all cases, a complete isomerization of the stereochemistry is observed and only the E-isomer is obtained. The reactivity of the resulting vinylic organometallic can be increased by a transmetalation reaction into organocopper, organozinc or organopalladium species and, therefore, several carbon-carbon formation were easily realized.
Thiol mediated 5-(π-endo)ortho vinyl radical cyclizations
Montevecchi, Pier Carlo,Navacchia, Maria Luisa
, p. 201 - 219 (2007/10/03)
The radical reaction of benzenethiol with alkynes 1a-o carried out at 154 °C affords a mixture of thiol/alkyne adduct 3 and benzothiophene 5, deriving from vinyl radical intermediates 2 through hydrogen abstraction and 5-(π-endo)(orthocyclization onto the
Radical Carbonylation of Alkynes in the Presence of Thiols
Nakatani, Shogo,Yoshida, Jun-ichi,Isoe, Sachihiko
, p. 880 - 881 (2007/10/02)
Treatment of alkynes with thiols under an atmosphere of carbon monoxide initiated by azobis(isobutyronitrile) (AIBN) gives β-alkylthio-α,β-unsaturated aldehydes.
STEREOSELECTIVE SYNTHESIS OF (E)-ALKENYLSILANES FROM ALDEHYDES WITH A REAGENT PREPARED BY CHROMIUM(II) REDUCTION OF Me3SiCHBr2
Takai, Kazuhiko,Kataoka, Yasutaka,Okazoe, Takashi,Utimoto, Kiitiro
, p. 1443 - 1446 (2007/10/02)
Aldehydes are converted to the corresponding (E)-alkenylsilanes with one carbon homologation by means of a gemdichromium reagent prepared by CrCl2 reduction of Me3SiCHBr2 in THF.Transformation of aldehydes into alkenyl sulfides is also achieved with a com
Synthesis of vinyl sulphides, azido sulphides, and olefins from β-hydroxy-sulphides
Dumont, Willy,Krief, Alain
, p. 673 - 675 (2007/10/02)
Vinyl sulphides, azido sulphides, and olefins have been prepared from β-hydroxy-sulphides via β-chloro-sulphides; the regio- and stereo-chemistry of these reactions is discussed.
