A novel palladium migration methodology for the synthesis of complex fused polycycles has been developed. This process involves 1,4-palladium alkyl to aryl migrations via through-space C-Hactivation, followed by intramolecular arylation or an intermolecular Heck reaction providing a very efficient way to synthesize fused ring systems.

What makes a good cavity? A molecular cavity enabled the stabilization of a selenenyl iodide (RSeI) intermediate formed in 5′‐deiodination of a thyroxine derivative by an organoselenol (see scheme). The chemical processes proposed for the iodothyroninedeiodinase catalytic cycle were experimentally established.

O-directed alkyne trans-haloboration using BX3 (X=Cl or Br) leads to C4-halogenated benzoxaborinines that are useful intermediates for accessing the core structure found in bicyclic boronate based β-lactamase inhibitors. A computational study identified two viable mechanisms to furnish the trans-haloboration products.
