Abstract
NHC-based pincers (NHC = N-heterocyclic carbene) have been broadly employed as supporting platforms, and their palladium complexes have found many synthetic applications. However, previous studies mainly focused on the NHC pincers of palladium featuring an oxidation number of +II. In contrast, oxidation of these well-defined Pd(II) species and the study of their fundamental high-valent Pd chemistry remain largely undeveloped. In addition, from a perspective of PdII/PdIV catalysis, the reactivity and degradation of NHC pincers in catalytically relevant reactions have not been well understood. In this work, a series of Pd(II) complexes supported by a well-known NHC^Aryl^NHC pincer platform have been prepared. Their reactivity towards various oxidizing reagents, including halogen surrogates, electrophilic fluorine reagents, and alkyl/aryl halides, has been examined. In some cases, ambient-characterizable high-valent Pd NHCs, which have been scarcely reported, were obtained. The carbenes incorporated into the pincer framework proved to be effective spectator donors. In contrast, the central aryl moiety exhibits versatile reactivity and collapse pathways, allowing it to function either as a spectator or a non-innocent actor.

Abstract
The metalation of the DIPPCCC (DIPPCCC = bis(diisopropylphenyl-imidazol-2-ylidene)phenyl) ligand platform with Pd was achieved under mild conditions by reacting [H3(DIPPCCC)]Cl2 with Pd(OAc)2 at room temperature in the presence of 3.1 equiv of LiN(SiMe3)2. The resulting complexes (DIPPCCC)PdX (X = Cl or Br) were oxidized by two-electron oxidants PhICl2, Br2, and BTMABr3. All the complexes were crystallographically characterized, and analysis of structural parameters around the ligand scaffold show no evidence of a ligand-centered radical, rendering the metal center in the oxidized species, (DIPPCCC)PdX3 (X = Cl or Br), a formal PdIV oxidation state. Unlike their NiIV analogues, these PdIV complexes are stable to air and moisture. The addition of styrene to (DIPPCCC)PdBr3 resulted in the clean reduction of PdIV to PdII, along with the formation of the halogenated alkane. The oxidation to PdIV and subsequent return to PdII upon reduction, as opposed to formation of PdIII species, showcases the accessibility of high-valent palladium DIPPCCC complexes.

Abstract
The last decade has witnessed the rapid development of high-valent Pd-involved organic transformations. This has also led to a steadily growing number of publications concerning the preparation of isolable and characterizable palladium(III) and palladium(IV) complexes. A variety of one-electron and two-electron oxidants have been employed to give access to high-oxidation-state Pd compounds. Undoubtedly, the study of these stoichiometric reactions has great implications for relevant Pd-mediated catalysis. In this minireview, the focus is on the synthetic approaches to structurally determined PdIII/IV complexes starting from their PdII precursors, and the advances in this research area from early 2010 to late 2019 will be highlighted. Chemical oxidations exploiting various oxidizing agents including 1) hypervalent iodine reagents; 2) halogens; 3) electrophilic fluorination reagents; 4) alkyl/aryl halides; 5) ferrocenium salts; 6) peroxides/O2 ; 7) sulfonyl chlorides; and 8) others are covered. A "greener" electrooxidation manner has also been reviewed.

Abstract
Oxidative addition of N-(2-iodophenyl)formamide to Pd(dba)2 (dba = dibenzylideneacetone) in the presence of 4,4'-ditertbutyl-2,2'-bipyridine ((t)Bubpy) produces [Pd(C6H4NHCHO-2)I((t)Bubpy)] (1) which inserts 2-iodophenyl isocyanide to give [Pd{C(=NC6H4I-2)C6H4NHCHO-2}I((t)Bubpy)] (2). Dehydroiodination of 2 with Tl(acac) (acacH = acetylacetone) gives the stable Pd(IV) complex OC-6-35-[Pd{C,N,N-C(=NC6H4-2)C6H4NCHO-2}I((t)Bubpy)] (4) likely resulting from the spontaneous oxidative addition of the I-Ar moiety present in the unstable intermediate Pd(II) complex [Pd{C,N-C(=NC6H4I-2)C6H4NCHO-2}((t)Bubpy)] (3). The crystal structure of 4 shows various C-H···O hydrogen bonds resulting in chains of dimers stacked along the a axis.

Abstract
Copper and palladium catalysts are critically important in numerous commercial chemical processes. Improvements in the activity, selectivity and scope of these catalysts could drastically reduce the environmental impact, and increase the sustainability, of chemical reactions. One rapidly developing strategy for achieving these goals is to use 'high-valent' organometallic copper and palladium intermediates in catalysis. Here we describe recent advances involving both the fundamental chemistry and the applications of these high-valent metal complexes in numerous synthetically useful catalytic transformations.
