Abstract

The reaction of α-thioketones and alkynes in the presence of a rhenium catalyst, [HRe(CO)4]n, gave γ-thio-α, β-unsaturated ketones in excellent yields. The alkynes were inserted into the carbon-sulfur bond of the α-thioketones, and isomerization of a double bond provided the products with high regio- and stereoselectivities. This reaction also proceeded in an intramolecular fashion.
