  1. 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.

  2. 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 …

    … 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 …
