Journal ArticleDOI
Highly stereospecific palladium-catalysed vinylation of vinylic halides under solid-liquid phase transfer conditions.
TL;DR: In this article, conjugated dienoates, dienones and dienals are obtained with high stereospecificity (⩾95%) and in high yields from the corresponding (E,E) and (Z) vinylic halides, and substrates (methyl acrylate, methyl vinyl ketone or acrolein).
Journal ArticleDOI
Heck-type reactions in water
TL;DR: In this paper, the presence of water is determined for the efficiency of quaternary ammonium salt (QX) in palladium-catalysed vinylation of organic halides using an alkali metal carbonate as the base, whether QX is a chloride, a bromide or a hydrogensulfate.
Journal ArticleDOI
Palladium-catalysed arylation of allylic alcohols: Highly selective synthesis of β-aromatic carbonyl compounds or β-aromatic α,β-unsaturated alcohols.
TL;DR: The outcome of the coupling of aromatic halides with allylic alcohols can be highly controlled and the reaction directed at will towards the formation of either β-aromatic carbonyl or β -aromatic α,β-unsaturated alcohol compounds as discussed by the authors.
Journal ArticleDOI
[Pd/Base/QX] catalyst systems for directing Heck-type reactions
Tuyet Jeffery,Marc D. David +1 more
TL;DR: Palladium-catalyzed arylation of 2,3-dihydrofuran can be directed at will by an appropriate selection of the [Pd/Base/QX] catalyst systems as discussed by the authors.
Journal ArticleDOI
Tetraalkylammonium salt-based catalyst systems for directing the arylation of vinyltrimethylsilane
TL;DR: A suitable choice of [Pd/MZ/QX] catalyst systems can allow to direct at will the arylation of vinyl trimethylsilane towards the formation of either (E)-trimethyl (2-arylethenyl) silanes or styrene derivatives as mentioned in this paper.
