The discovery of new oxidation states of transition metals is rare. In his Perspective, Crabtree highlights the discovery of such a new state, Pd(VI), by Chen et al. The work may open up new avenues in organometallic chemistry. 
The combined use of cationic palladium(II) with a surfactant for the C–H functionalization of indoles and pyrroles in water
Abstract The utility of electrophilic palladium(II) species was demonstrated for C–H bond functionalization of indoles and pyrroles in water. The system displayed attractive features that areExpand

Synthesis, structural characterization and reactivity towards phenol of a bis(silyl) platinum(II) complex
Abstract The reaction of 1,2-C6H4(SiMe2H)(SiH3) (1) with Pt(dmpe)(PEt3)2 (dmpe = Me2PCH2CH2PMe2) in the ratio of 1:1 yields the complex {1,2-C6H4(SiMe2)(SiH2)}PtII(dmpe) (2), which has uniqueExpand
Reactivity of [1],[1]disilamolybdenocenophane toward zerovalent platinum complexes.
TLDR
Treatment of the molybdenum compound with 2 equiv of [Pt(PCy(3))(2)] results in a trinuclear cluster, and structural parameters suggest the formulation as the sigma-complex of a Mo-Si bond. Expand
Gold-silane and gold-stannane complexes: saturated molecules as sigma-acceptor ligands.
TLDR
The straightforward synthesis and complete characterization of three gold complexes supported by diphosphino silane and stannane ligands is reported, providing unambiguous evidence for the existence of complexes of type C, in which a saturated Group 14 element could behave as an end-on, s-acceptor ligand toward a transition metal.

Synthesis and Structure of Formally Hexavalent Palladium Complexes
TLDR
Formally hexavalent palladium complexes have been isolated and structurally characterized for the first time and single-crystal x-ray analysis revealed that each of the central palladium atoms of the complexes is ligated by six silicon atoms and is Hexavalent, whereas the other palladium atom are divalent.
