Rhodium(III)‐Catalyzed Synthesis of Skipped Enynes via C(sp³)–H Alkynylation of Terminal Alkenes

The Rh III ‐catalyzed allylic C−H alkynylation of non‐activated terminal alkenes leads selectively to linear 1,4‐enynes at room‐temperature. The catalytic system tolerates a wide range of functional groups without competing functionalization at other positions. Similarly, the vinylic C−H alkynylation of α,β‐ and β,γ‐ unsaturated amides gives conjugated Z‐1,3‐enynes and...
