Unsaturated N‐sulfonamides undergo a RhIII‐ catalyzedallylicC(sp3)H activation followed by insertion with an exogenous internal alkyne. The reaction generates [3.3.0], [4.3.0], and [5.3.0] azabicyclic structures with excellent diastereoselectivity. Deuterium labeling experiments implicate a 1,3‐Rh shift as a key step in the mechanism.

A room-temperature intramolecular oxy- and aminoarylation of alkenes with aryldiazonium salts has been developed using a novel gold and photoredox dual-catalytic system. The compatibility of these two catalytic modes has been established for the first time and demonstrates the potential of this system as a method to expand the scope of nucleophilic addition reactions to carbon-carbon multiple bonds

Homogeneous carboamination, carboalkoxylation and carbolactonization of terminal alkenes are realized via oxidative gold catalysis, providing expedient access to various Substituted N- or O-heterocycles. Deuterium-labeling studies established the anti nature of the alkene functionalization and the indispensible role of Au(I)/Au(III) catalysis. This study constitutes the first example of catalytically converting C(sp(3))-Au bonds into C(sp(3))--C(sp(2)) bonds in a cross-coupling manner and opens new opportunities to Study gold alkene catalysis where alkylgold intermediates can be readily functionalized intermolecularly.
