Oxidatively induced reductive elimination (OIRE) is a powerful strategy for the formation of carbon–carbon bonds and has been widely employed in late transition metal catalysis. In contrast, early tra...

Mass-selected Ptn+ (n ≤ 7) were deposited at variable energies on highly oriented pyrolytic graphite (HOPG), creating highly active hydrogen evolution reaction (HER) electrocatalysts. HER mass activit...

The conversion of carbon dioxide into value-added products has emerged as an alternative method to achieve net-zero emissions. While technologies that transform CO2 into fuels and chemical feedstocks ...

Atactic polystyrene is a commonplace transparent thermoplastic with a high glass transition temperature (Tg ∼ 100 °C), but its nondegradable backbone leads to detrimental environmental accumulation. Poly(hydroxyalkanoates) (PHAs) have emerged as biodegradable polyester alternatives to conventional olefinic plastics, but only a few PHAs possess the high Tg values (>100 °C) characteristic of polystyrene. Herein, we report the synthesis of phenyl-substituted poly(3-hydroxybutyrates) (PhPHBs) via sequential catalytic carbonylation and zinc-mediated ring-opening polymerization (ROP). Both cis and trans isomers of α-phenyl-β-butyrolactone (α-Ph-β-BL) were synthesized and polymerized to provide 13 distinct PhPHBs of varying trans incorporation and their resulting properties were systematically studied. The PhPHBs exhibit high and tunable Tg values (104–128 °C) and high thermal stability. We anticipate this work will inform the design of future high Tg PHAs as degradable alternatives to polystyrene.

We report changes in the reactivity profile of a high-spin, terminal ferrous hydroxo complex (EmL)Fe(OH) as a function of oxidation states (i.e., FeII/FeIII). The terminal, high-spin Fe–OH adducts wer...
