  • Asymmetric dioxygenation of alkenes is an attractive concept to synthesize enantioenriched diols, but the performance in the case of terminal alkenes is low with current methods. Now, this has been addressed by an asymmetric oxypalladation process that provides access to enantioenriched 1,2-diols, enabled by the chiral 6-modified pyridinyl oxazoline ligand.

  • Installation of difluoroalkyl groups while also imparting stereochemical information is mostly only possible with organocatalytic methods that activate carbonyls. Here the authors show a method to perform an difluoroallylation of hydrazones, forming a masked amine stereocenter, via palladium- and N-heterocyclic-carbene catalysis.

  • Rare-earth monometallic phosphinidene complexes have been elusive synthetic targets. Here, the authors describe the synthesis and tunable reactivity of two scandium phosphinophosphinidene complexes containing very unusual Sc-P multiple bonds.

  • Difluorocarbene transfer is mostly limited to reactions that utilize its intrinsic electrophilicity. Now, a controllable palladium-catalysed difluorocarbene transfer reaction is reported that involves nucleophilic and electrophilic palladium difluorocarbene species. The selective reactions between arylboronic acids and the difluorocarbene precursor BrCF2PO(OEt)2 give four different products—difluoromethylated and tetrafluoroethylated arenes and their corresponding fluoroalkylated ketones.
