The synthesis and characterization, as well as photoluminescent and electrochemical features of a series of ionic copper(I) complexes?, i.e., [Cu(N^N)(P^P)]+, where N^N is 4,4?-diethylester-2,2?-biquinoline (dcbq) and P^P is bis-triphenylphosphine, bis[2-(diphenylphosphino)phenyl)ether] (POP), or 4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (Xantphos)?are reported along with their application to achieve both deep-red and white light-emitting electrochemical cells (LECs). In short, the first deep-red Cu(I)-based LECs featuring high irradiances (?100 muW cm?2) and excellent color stability (x/y CIE color coordinates of 0.66/0.32) over days are reported. This is achieved by comparing the electroluminescent behavior of this series of complexes with respect to the irradiance and stability, as well as the impact of introducing supporting electrolytes on the device performance. This is rationalized using spectroscopic and electrochemical studies. Finally, the first white-emitting LEC is manufactured with red-emitting copper(I) complexes, achieving x/y CIE color coordinates of 0.31/0.32 and a high color rendering index of 92.

Developing new catalytic technologies to utilize biomass as the carbon source of chemical and material industries attracts more attention than ever because of the rapid depletion of fossil feedstock and strong societal demand. This work presents the aqueous carbonylation of bioderived 5-bromofuroic acid to afford 2,5-furandicarboxylic acid in the presence of a supported palladium catalyst. The expected 2,5-furandicarboxylic acid product was isolated in >95% yield even after reusing the catalyst 10 times. This novel protocol not only provides an alternative synthetic route to 2,5-furandicarboxylic acid complementary with the tricky 5-HMF oxidation but also offers a promising market for the underexploited hemicellulose-derived furfural platform.

A reaction mode on carbene bridging C?H activation (CBA) is described. In this reaction, metal carbene was produced prior to the event of C?H bond metallation. Readily available aryl dizaoesters were employed as the carbene precursors. Migratory insertion of the palladium carbene intermediate could create a modular bridging arm to promote the C?H bond palladation of tethered aldehyde moiety. Its synthetic potential was demonstrated by facile construction isocoumarin scaffold from easily accessible starting materials. Furthermore, this protocol is also amenable for late-functionalization of complex molecules.

A palladium-catalyzed thiocarbonylation of styrene derivatives is reported for the first time. The combination of thiols as nucleophiles and a bidentate ligand ensures a unique reaction outcome with high regioselectivity toward the more valuable branched isomer and new reactivity. The ambient reaction conditions (temperature, catalyst loading) and the use of a CO surrogate render this transformation a useful method for the synthesis of thioesters from available feedstock. Various functional groups on arene and thiol substituents are tolerated by the system. Notably, challenging ortho-substituted styrenes are converted with unprecedentedly high regioselectivity.
