A facile regio- and stereocontrolled synthesis of (E)-disubstituted vinyl sulfones via transformation of alkenylzirconocenes with sulfonyl chlorides
Duan, De-Hui,Huang, Xian
, p. 317 - 318 (2007/10/03)
Alkenylzirconium reagents, readily obtained by hydrozirconation of terminal alkynes, can smoothly react with sulfonyl chlorides to afford (E)- disubstituted vinyl sulfones in moderate to good yields. Some γ- functionalized vinyl sulfones can be also conve

The radical chain addition of tosyl iodide to some alkenes has been studied.The reaction was carried out at room temperature under visible light, giving the usual high yields of β-iodo sulfones.These adducts were transformed into the corresponding unsatur
"Syn-Effect" in the Conversion of (E)-Vinylic Sulfones to the Corresponding Allylic Sulfones
Hirata, Takaki,Sasada, Yoshihiro,Ohtani, Takashi,Asada, Takahiro,Kinoshita, Hideki,et al.
, p. 75 - 96 (2007/10/02)
It was found that (E)-vinylic sulfones preferentially afford (Z)-allylic sulfones as kinetically-controlled products by treatment with a base under mild conditions, while (Z)-vinylic sulfones give (E)-allylic sulfones.Such stereochemical relationship was
A SIMPLE METHOD FOR THE SYNTHESIS OF γ-FUNCTIONALIZED VINYL AND ALLYL SULFONES
Najera, Carmen,Perez-Pinar, Alfonso,Sansano, Jose M.
, p. 6337 - 6352 (2007/10/02)
The synthesis of γ-functionalized vinyl sulfones 3 have been carried out directly starting from dibromides 2 derived from allyl sulfones 1 by reaction with different nucleophiles.The process is stereoselective affording compounds 3 with E configuration ex
