A novel and efficient procedure for the synthesis of δ,γ- alkynyl esters by the conjugate addition of alkynylsilanes to acrylate esters in the presence of a catalytic amount of indium(III) chloride has been developed. This method provides a rapid and efficient access to substituted δ,γ-alkynyl esters.

ω-Acetylenic acids, substituted or not at their acetylenic end, could be efficiently cyclized to γ- or δ-alkylidene lactones in the presence of AuCl and K2CO3. In contrast AuCl3 led to lactone dimers, probably through cycl
Ruthenium/halide catalytic system for C-C bond forming reaction between alkynes and unsaturated carbonyl compounds

A ruthenium complex [triruthenium dodecacarbonyl, Ru3(CO) 12] in the presence of bis(triphenylphosphine)iminium chloride ([PPN]Cl) catalyzes the conjugate addition of terminal alkynes to alkyl acrylates to give high yields of γ,δ-alkynyl esters. On the other hand, the linear codimerization reaction of terminal alkynes with alkyl acrylates proceeds in the presence of a catalytic amount of Ru 3(CO)12 and lithium iodide to give the corresponding conjugate dienes. These two different types of catalytic carbon-carbon bond forming reactions are controlled only by the nature of halide ions, either a chloride or an iodide, with other conditions being kept almost the same.

The addition of terminal alkynes to acrylate esters in the presence of a ruthenium catalyst and chloride sources proceeds to give the corresponding γ,δ-alkynyl esters in good yields.
