Mechanically triggered on-demand degradation of polymers synthesized by radical polymerizations

Nature Chemistry, Published online: 12 April 2024; doi:10.1038/s41557-024-01508-xRadical polymerizations yield polymers that cannot easily be degraded. The co-polymerization of cyclobutene-based monomers with conventional vinyl monomers has now been shown to result in co-polymers with cyclobutane mechanophores in their backbone, which facilitate on-demand...

Bioorthogonal masked acylating agents for proximity-dependent RNA labelling

Nature Chemistry, Published online: 09 April 2024; doi:10.1038/s41557-024-01493-1RNA localization is key to regulating cellular function but is challenging to measure in an unbiased manner. Now a combination of enol-masked acylating probes with a bioorthogonal esterase to locally unmask them provides a non-radical RNA proximity labelling platform—termed...

Upcycling of polyethylene to gasoline through a self-supplied hydrogen strategy in a layered self-pillared zeolite

Nature Chemistry, Published online: 09 April 2024; doi:10.1038/s41557-024-01506-zThe development of new methodologies to convert plastics into fuels without relying on noble metal-based catalysts is desirable. Now it is shown that a layered self-pillared zeolite enables the conversion of polyethylene to gasoline with a selectivity of 99% and yields...

Masked acid chlorides for proximity labelling of RNA

Nature Chemistry, Published online: 09 April 2024; doi:10.1038/s41557-024-01492-2A non-radical proximity labelling platform — BAP-seq — is presented that uses subcellular-localized BS2 esterase to convert unreactive enol-based probes into highly reactive acid chlorides in situ to label nearby RNAs. When paired with click-handle-mediated enrichment and...

Copper-catalysed asymmetric hydroboration of alkenes with 1,2-benzazaborines to access chiral naphthalene isosteres

Nature Chemistry, Published online: 08 April 2024; doi:10.1038/s41557-024-01505-0Chiral 1,2-benzazaborines are promising isosteres of naphthalene, but rarely explored due to the lack of efficient synthetic methods. Now, the copper-catalysed enantioselective hydroboration of alkenes with 1,2-benzazaborines has been developed, providing a general platform...

Tetrameric self-assembling of water-lean solvents enables carbamate anhydride-based CO<sub>2</sub> capture chemistry

Nature Chemistry, Published online: 08 April 2024; doi:10.1038/s41557-024-01495-zCarbon capture, utilization and storage is key for climate change mitigation and developing more environmentally friendly technologies. Now it has been shown that CO2 capture in single-component water-lean solvents is accompanied by the self-assembly of reverse-micelle-like...
