This work describes the first systematic evaluation of proximal functionality's effect on the equilibrium constant of the allylicaziderearrangement. We report three series of allylicazides to describe the equilibrium of hydroxy-crotyl azide.

The gold(I)‐catalysed cycloisomerisation of appropriately substituted 1,6‐cyclopropene‐enes proceeds through regioselective electrophilic ring opening of the three‐membered ring to generate an alkenyl gold carbenoid that achieves the intramolecular cyclopropanation of the remote olefin. This strategy allows straightforward, highly efficient and diastereoselective access to a variety of substituted
An organocatalytic cross-coupling of allyl bromides and arylboronicacids was developed using a designer thioether catalyst. Preliminary mechanistic studies suggested the involvement of a key sulfoxonium ylide that binds to the arylboronicacid and triggers 1,2-aryl migration.
