Palladium-catalysed annulation of β-chloro-α,β-unsaturated esters with internal alkynes leading to 2H-pyran-2-ones
Hua,Tanaka
, p. 179 - 184 (2001)
Heteroannulation of β-chloro-α,β-unsaturated esters with internal alkynes proceeded in the presence of triethylamine and palladium complexes, bis(triphenylphosphine)palladium species in particular, to afford to 2H-pyran-2-ones. Treatment of methyl (Z)-3-c
One-pot tandem hydrophenylation and ionic hydrogenation of 3-phenylpropynoic acid derivatives under superelectrophilic activation
Nilov, Denis I.,Vasilyev, Aleksander V.
, p. 5714 - 5717 (2015/09/29)
The reactions of esters and amides of 3-phenylpropynoic acid with strong Lewis acids AlX3 (X = Cl, Br) or conjugate Br?nsted-Lewis superacids HX-AlX3 (X = Cl, Br) in benzene and cyclohexane at room temperature afforded 3,3-diphenylpropanoic acid derivatives in up to 94% yield. This tandem reaction of the acetylene bond proceeded by hydrophenylation followed by ionic hydrogenation.
Chloroesterification of enynes catalyzed by NHC rhodium compounds
Ji, Young Baek,Sang, Ick Lee,So, Hee Sim,Young, Keun Chung
, p. 551 - 554 (2008/12/21)
An efficient rhodium N-heterocyclic carbene (NHC)-catalyzed chloroesterification of terminal alkynes and enynes has been developed. The reaction was highly regio- and stereospecific: the Z-isomer was obtained as the sole product. Georg Thieme Verlag Stutt
General and selective synthesis of (Z)-3-haloacrylates via palladium-catalyzed carbonylation of terminal alkynes

, p. 477 - 479 (2007/10/03)
(Chemical Equation Presented) A general and selective palladium-catalyzed carbonylation of terminal alkynes method for the synthesis of (Z)-3-haloacrylates is presented. In the presence of a catalytic amount of PdX2 and 5 equiv of CuX2/su
Novel stereospecific synthesis of 3-chloroacrylate esters via palladium- catalyzed carbonylation of terminal acetylenes
Li, Jinheng,Jiang, Huanfeng,Feng, Aiqun,Jia, Lanqi
, p. 5984 - 5987 (2007/10/03)
A simple and effective method for the highly regio- and stereospecific synthesis of (Z)-3-chloroacrylate esters is described. Using terminal acetylenes and primary, secondary, and tertiary aliphatic alcohols as substrates, the carbonylation reactions were
ELECTROCHEMICAL CROSS-COUPLING OF ORGANIC HALIDES: TRICHLORMETHYLATION AND RELATED SYNTHESIS OF GEM-DICHLORO COMPOUNDS
Nedelec, J. Y.,Ait-Haddou-Mouloud, H.,Folest, J. C.,Perichon, J.
, p. 1699 - 1700 (2007/10/02)
The cross-coupling of activated alkyl halides with carbon tetrachloride or substituted trichloromethanes can be obtained electrochemically in good yield in an undivided cell with a sacrificial anode.
Electrochemical Cross-Coupling of Alkyl Halides in the Presence of a Sacrificial Anode
Nedelec, Jean-Yves,Mouloud, Hassan Ait Haddou,Folest, Jean-Claude,Perichon, Jacques
, p. 4720 - 4724 (2007/10/02)
The electrochemical trichloromethylation of various alkyl halides has been obtained in high yields in an undivided cell in the presence of a sacrificial anode.This cross-coupling process has been extended to the preparation of numerous gem-dichloro compounds from trichloro-substituted methanes and alkyl halides.Zinc,magnesium or aluminium were used as anodes according to the reduction potentiel of the reagents.Mixtures of polar aprotic solvents,e.g.THF-TMU or THF-NMP, were found more appropriate than pure solvents.The critical role of the metallic ions from the consumption of the anode has been clearly evidenced.
