Abstract
The activation of C–C bonds via transition metal catalysis has become an increasingly
popular strategy in organic synthesis. An emerging method to cleave C–C bonds is to
facilitate a β-carbon elimination using rhodium or palladium catalysis. This elementary
step typically relies on a thermodynamic driving force, such as the relief of ring
strain or steric strain. More recently, the use of neopentyl metal species or chelation
assistance has enabled this difficult transformation. This review will cover recent
synthetic applications of β-carbon eliminations under palladium and rhodium catalysis.
