Nickel-Catalyzed Direct Coupling of Allylic Alcohols with Organoboron Reagents
Wang, Gaonan,Gan, Yi,Liu, Yuanhong
, p. 916 - 920 (2018)
The direct coupling of allylic alcohols with arylboronic acids or their derivatives catalyzed by Ni(cod)2 in the presence of a catalytic amount of base has been developed. A wide variety of allylic substrates or arylboronic acids turned out to be applicable to this catalytic system. The present method does not require the use of ligands for stabilizing the nickel catalyst in most cases or additional activators for activation of allylic alcohols.
Zinc homologation-elimination reaction of α-sulfinyl carbanions as a new route to olefins
Abramovitch, Adi,Marek, Ilan
experimental part, p. 4924 - 4931 (2009/05/27)
α-Lithiosulfinyl carbanions react either intermolecularly, after transmetalation into an organocopper derivative in an SN2-type process, with zinc carbenoids, or intramolecularly by higher-order zincates through a tandem zinc homologation-β-elimination reaction into the corresponding alkenes. α,α- and α,β-Disubstituted alkenes can also be produced through these two methodologies.

A synthesis of enantiomerically enriched propargyl silanes
Fleming, Ian,Mwaniki, Joseph M.
, p. 1237 - 1247 (2007/10/03)
Reduction of ethyl 3-methyl-, 3-isopropyl- and 3-n-pentyl-3-[dimethyl(phenyl)silyl]propanoates 4 with DIBAL to the aldehydes 5, enol trifluoromethanesulfonate (triflate) formation using trifluoromethanesulfonic (triflic) anhydride and 2,6-di-tert-butylpyridine, and elimination using LDA, gives the propargyl silanes 8. The esters 4 could also be prepared enantiomerically enriched (11), and the final products are the enantiomerically enriched propargyl (homochiral) silanes 14.
GLYCOL-CLEAVAGE REAGENTS ALSO ACT ON STANNYLENE DERIVATIVES
David, Serge,Thieffry, Annie
, p. 2885 - 2888 (2007/10/02)
The well-known cleavage reactions of vicinal diols by such reagents as Pb(OAc)4, NaIO4, PhI(OAc)2 and Ph3BiV-compounds have now been observed for the first time on covalent derivatives of these vicinal diols, their dibutylstannylenes.
