Anodic olefin couplingreactions using a tosylamine trapping group have been studied. The cyclizations are favored by the use of a less-polar radical cation and more basic reaction conditions. The most significant factor for obtaining good yields of cyclic product is the use of the more basic reaction conditions. However, a number of factors including the nature of both the solvent and the electrolyte

A stereochemical substrate probe was used to assess the factors that affect the stereochemicalcourse of nucleopalladation in the context of an enantioselective Wacker‐type reaction. The enantioselectivity correlates directly with the nucleopalladation pathway, and both the neutral‐donor and anionic ligands on palladium are capable of controlling selectivity for cis‐ or trans‐nucleopalladation (see
