Abstract:

Oxidative addition and reductive elimination are two fundamental steps common to many different catalytic reactions.  Insertion into C-X bonds is particularly prevalent as one of the first steps in a catalytic cycle.

We have been exploring the synthetic potential associated with reversible oxidative addition into carbon-halogen bond and recently developed a metal catalyzed carboiodination reaction (1-2). This lecture will describe the scope and limitations of the reaction including recent work that has expanded the scope and led to the development of a metal catalyzed hydrohalogenation reaction (3).  

C-H functionalization remains one of the most active areas of research. We will present our recent work in this field highlighting C-H bond activation as a key step in spirocyclization reactions (4-5).
