of paramount importance in synthesis. A particular focus has been the generation of organoboranes, organosilanes and organostannanes from simple hydrocarbons (X=B, Si, Sn). Despite the importance of organozinc compounds (X=Zn), their synthesis by the catalytic functionalisation of C−H bonds remains unknown. Herein, we show that a palladium catalyst and zinc hydride reagent can be used to transform C−H

A range of mixed biphosphine complexes of palladium(0) has been prepared and characterized by P-31 NMR spectroscopy. The complexes disproportionate in solution at rates which depend on the nature of the ligands. The structure of [Pd(dcpe)(dppe)] has been established in an X-ray diffraction study.
