Shedding Light on the Precatalytic Mixture of Pd(OAc)2 and Cooperating Bipyridone Ligands for the C─H Functionalization of Arenes

ChemCatChem, EarlyView.
The reactions of the common palladium precursors Pd(OAc)2 and PdCl2 and cooperating bipyridone ligands leads to well defined complexes which are general precatalysts for the direct C─H arylation of arenes, more active than Pd(OAc)2/ligand mixtures in nonpolar solvents.

Asymmetric Organocatalytic Synthesis of Sulfone‐Containing (Dihydro)pyrans via Formal (4+2)‐Cycloadditions of Allenylsulfones or Propargylsulfones and Michael Acceptors

ChemCatChem, Accepted Article.
The activation of electron poor allenes with Lewis base catalysts allows for unique transformations and chiral isochalcogenoureas were recently introduced as powerful catalysts for allenoate‐based (4+2)‐cycloadditions. We herein now report the use of these catalysts for the activation and control of allenylsulfones and propargylsulfones for asymmetric (
