A new method efficiently adds C−C and C−S bonds to terminal alkynes, allowing for accessing a range of β-substituted α,β-unsaturatedketones. The versatility of the approach lies in its ability to tune the reaction conditions to target different positions of the alkyne by switching temperature.

The preparation and reduction of β-arylthio- or β-alkylthio-αβ-unsaturatedketones (1) with lithium aluminium hydride or sodium borohydride have been examined. Reduction of the ketones (1) with lithium aluminium hydride gave αβ-unsaturated ketones (2), in which the olefinic (R1) and carbonyl (R2) substituents are reversed compared with the starting αβ-unsaturated ketone (1), or the saturated γ-hydroxy-sulphides
