Cross Coupling of Alkenyl Gold Complexes with Alkyl Electrophiles and Nickel Catalyzed Hydroarylation of Alkenes
… second reaction described is a nickel catalyzed hydroarylation of alkenes. We are able to achieve good anti-Markovnikov selectivity with a wide range of alkenes, including styrenes, alkyl substituted alkenes, and enol ethers.

Zirconium-mediated alkyene-aldehyde coupling, rhodium-catalyzed alkene hydrothiolation, and copper-catalyzed alkyne hydroarylation: Reaction development and mechanistic investigations
In the last 150 years, we have seen a boon in the development of new methodologies for the synthesis of organic compounds, which has led to the ability for one to synthesize any compound of interest given enough time and resources. Of course, time and resources are finite, thus development of …

Conjugated polymer based materials via the incorporation of polymerizable units
… and end-capped with norbornene using the hydroarylation reaction. These norbornene end-capped CPs became macroinitiators using Grubbs' catalysts, and they were used to prepare block copolymers by polymerizing ROMP monomers.

Gold(I) and Platinum(II)-Catalyzed Hydrofunctionalization of Allenes and Alkenes with Carbon and Nitrogen Nucleophiles
… carbene complex catalyzed the intermolecular hydroarylation of allenes with indoles to form (<italic>E</italic>)-allylic indoles in modest to good yield at room temperature. The protocol was effective for monosubstituted, 1,3-disubstituted, and tetrasubstituted allenes and various indoles.</p> …

The design and synthesis of polymeric assemblies for materials applications : chemosensing, liquid crystal alignment and block copolymers
… of cross-coupling polymerizations using the hydroarylation of norbornadiene. This reaction is shown to be an efficient approach to generating macroinitiators which can be further polymerized using ring opening metathesis polymerization. These end-capped materials can also be crosslinked into …

Total synthesis of oxaphenalenone natural products
… by an interesting Au(I)-mediated 6-endo-dig hydroarylation. Subsequent studies implemented closely-related synthetic operations to assemble a masked ortho-quinone methide (o-QM) bearing the OP framework via interrupted Rieche formylation. The masked o-QM intermediate was utilized in the …

Computational Studies of Selected Ruthenium Catalysis Reactions.
… pathways are particularly relevant to catalytic hydroarylation of olefins. These processes involved the +2 to +3 oxidation of ruthenium and its effect on ruthenium-carbon bond strengths, carbon-hydrogen bond activation by 1,2-addition/reductive elimination pathways appropriate to catalytic …

The chemistry of gold with unsaturated organics: coordination, activation and catalysis
… 1H NMR monitoring of gold(III)-catalysed hydroarylation reactions revealed that silver salts do not act as a simple chloride scavengers, but identification of the gold species in solution was unsuccessful. In addition, a family of highly electrophilic fluorosulfonium and fluorobismuthium …

Photochemical synthesis of dihydroquinolinones and their investigation toward macrocycle synthesis via ring expansion
… and others through a formal C(sp2)-H/C(sp3)-H hydroarylation.2–5 However, none of these methods have reported such syntheses producing the N-unsubstituted DHQ — which is required for the SuRE. Thus we first set out to optimise this photochemical cyclisation to enable the direct formation of …
