  • Depolymerising polyolefins typically requires high temperatures and is energy intensive. Here, the authors upcycle PVC into a photothermal agent which could depolymerise polyolefins using sunlight into low molecular weight waxes or monomers

  • Developing new transformations of bulky chemicals is an important approach to expand the horizons of current chemistry. Instead of traditional hydroarylation of dienes, the authors herein demonstrate a nickel-catalyzed arylative telomerization of isoprene with high chemo- and regioselectivities.

  • A wearable capacitive temperature sensor that is based on exceptional-point-enhanced phase sensing can measure temperatures from 36 °C to 55.5 °C—a perturbation from 0% to 3.95%—with a maximum normalized sensitivity of 400, an estimated dynamic range of 53.52 dB and an estimated signal-to-noise ratio of 63.8 dB.

  • Cyclotelomerization of isoprene can lead to many isomers and controlling the selectivity in this reaction has been challenging for chemical methods. Now, Ni-catalysed nucleophilic cyclotelomerization of isoprene with heterocycles provides cyclic monoterpene derivatives with high selectivity.

  • Metallocene-based phosphines are compounds with potential use in catalysis. Here, the authors report the electrochemical regioselective functionalization of group 8 metallocenes with phosphine oxides; over 60 examples of phosphorylated (benzo)ferrocenes and ruthenocenes can be accessed via this method without the need for a preinstalled directing group.

  • The Mizoroki–Heck reaction and its reductive analogue are staples of organic synthesis, but the ensuing products often lack a chemical handle for further transformation. Here the authors present a method to add a heterocycle and transformable halide across a double bond via iridium photocatalysis.

  • Butafulvene is a constitutional isomer of benzene, comprising a cyclobutene skeleton bearing two exocyclic conjugated methylene units. Strategies for the synthesis of butafulvene compounds are currently limited due to its intrinsic high strain energy and anti-aromaticity. Now, palladium-catalysed couplings have been developed for the rapid assembly of symmetric and non-symmetric anti-aromatic butafulvene derivatives.

  • Visible-light photocatalysis has evolved as a powerful technique to enable controllable radical reactions and the exploration of new photocatalytic mode for product diversity is of great significance. Herein, the authors present a photo-induced chemoselective 1,2-diheteroarylation of unactivated alkenes utilizing halopyridines and quinolines.

  • Developing efficient strategies to realize divergent arylation of dienes has been a longstanding synthetic challenge. Herein, a nickel-catalyzed divergent Mizoroki–Heck reaction of 1,3-dienes has been demonstrated through the modification of ligands and additives.

  • The presence of halogens in halogenated organic pollutants has negative impacts on the environment; however, they serve as valuable sources for halogenation reactions. Now it has been shown that transfer chlorination reactions enable the repurposing of halogenated organic pollutants for the synthesis of chlorides and bromides.
