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

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
Novel stereospecific synthesis of 3-chloroacrylate esters via palladium- catalyzed carbonylation of terminal acetylenes
Li, Jinheng,Jiang, Huanfeng,Feng, Aiqun,Jia, Lanqi

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
