Significance

An indium-catalyzed syn-addition of 1,3-dicarbonyl compounds and 1-iodo-1-alkynes gives exclusively E-iodoalkenes in good yields for a variety of dicarbonyls and alkynes. The vinyl iodide that is formed can be further functionalized using a Sonogashira or a Suzuki coupling in a one-pot or two-pot procedure.
