Shenawi-Khalil, Sanaa,Sonavane, Sachin U.,Sasson, Yoel
, p. 2295 - 2297 (2012/07/27)
Phase-transfer catalyzed preparation of acetylenes from the corresponding vicinal dibromo compounds via double dehydrobromination using the mild solid base, anhydrous potassium phosphate, under very mild conditions is reported.
Cross-coupling of nonactivated alkyl halides with alkynyl grignard reagents: A nickel pincer complex as the catalyst
Vechorkin, Oleg,Godinat, Aurélien,Scopelliti, Rosario,Hu, Xile
supporting information; experimental part, p. 11777 - 11781 (2012/01/19)
In a pinch: The nickel pincer complex 1 catalyzes the cross-coupling of the title compounds with remarkable substrate scope and functional group tolerance. A nickel/alkynyl species was isolated and shown to be catalytically competent. THF=tetrahydrofuran, O-TMEDA=bis[2-(N,N-dimethylaminoethyl)] ether. Copyright
Nucleophilic vinylic substitutions of (Z)-(2-aroyloxyvinyl)phenyl- λ3-iodanes with tetrabutylammonium halides: Vinylic S N2 reactions and ligand coupling on iodine(III)
Ochiai, Masahito,Nishi, Yoshio,Hirobe, Masaya
, p. 1863 - 1866 (2007/10/03)
Treatment of (Z)-(β-benzoyloxyvinyl)phenyl-λ3- iodanes, readily prepared from ethynyl(phenyl)(tetrafluoroborato)- λ3-iodane via stereoselective Michael-type addition of benzoic acids in methanol in the presence of sodium benzoates, with tetrabutylammonium halides in THF at 65°C results in a vinylic SN2 reaction to give the inverted (E)-β-benzoyloxyvinyl halides in high yields.
