A catalyst system formed in situ from bis(2-methylallyl)cycloocta- 1,5-dieneruthenium(II) ((cod)Ru[met](2)), a phosphine, and scandium(III) trifluoromethanesulfonate (Sc-(OTf)(3)) was found to efficiently catalyze the anti-Markovnikov addition of imides to terminal alkynes, allowing mild and atom-economic synthesis of enimides. Depending on the phosphine employed, both the (E)- and the (Z)-isomer can be accessed stereoselectively.
