Biomolecular condensates formed by liquid-liquid phase separation (LLPS) are emerging as a critical organizing principle for synaptic compartmentalization. Aliphatic alcohols are commonly used to disrupt LLPS in biochemical studies and in cells. Here, we tested the impact of aliphatic alcohols at the organismal level in . We observe that aliphatic alcohols impair swimming behavior in wild-type controls but not in RIM/ UNC-10 mutant strains. Thus, our results suggest an correlate to the previously reported role of RIM liquid condensates in synaptic function in reduced systems.

The low-temperature oxidation of alkanes and arenes using molecular oxygen under ambient conditions is still one of the grand challenges of catalysis. Inspired by the alkane hydroxylation activity of the copper-based metalloenzyme, particulate methane monooxygenase, a tetra-copper polyoxometalate, [Cu(HO)(PWO)], was investigated as an electrocatalyst for the cathodic (reductive) oxidation of hydrocarbons with emphasis on oxidation of ethane. Controlled potential electrolysis (CPE) in water at -0.

We report here an efficient and sustainable protocol for the direct synthesis of 2,3-dihydroperimidine derivatives dehydrogenative C-N coupling, utilizing a recyclable Fe single-atom catalyst supported on nitrogen-doped carbon (Fe-N-C). The catalyst was synthesized by encapsulating ferrocene within the ZIF-8 framework, followed by pyrolysis. The catalyst exhibited excellent activity, stability, and recyclability, facilitating the transformation of diverse primary alcohols, including aryl/heteroaryl methanol and aliphatic alcohols, into the desired products in moderate to good yields.

The regioselective functionalization of C─H bonds at positions with nearly identical chemical environments remains a pivotal challenge in synthetic chemistry. While conventional hydrogen atom transfer (HAT) strategies dominate current methodologies, their limitations in selectivity drive the pursuit of alternative mechanisms. Here, we report a photoelectrochemically cooperative catalytic system mediated by a polypyridyl cobalt catalyst, enabling highly regioselective α-heteroarylation of ethers, alcohols, and amides.

: Carbohydrate-derived chiral ligands are promising tools in asymmetric catalysis due to their structural diversity, chirality, and availability. However, ligands based on galactose or sorbose have been scarcely explored in the enantioselective addition of dialkylzinc reagents to aldehydes. : A series of chiral diols and β-amino alcohols was synthesized from methyl D-glucopyranoside, methyl D-galactopyranoside, and D-fructose.

In this report, we present a sustainable, eco-friendly, practical, and cost-effective one-pot three-component reaction for the synthesis of a diverse library of highly substituted pyrimidines from amidines, primary alcohols, and aromatic ketones, catalyzed by a cobalt(III) complex. The well-defined cobalt(III) complex [Co(III)BPMAP-O]ClO is derived from a redox-active phosphine-free, pentadentate mono-carboxamide ligand (BPMAP-H), and is formed in situ from various cobalt(II) sources, including CoCl·6HO, CoBr, Co(NO)·6HO, Co(OAc)·4HO via oxygen activation. Using aromatic ketones and benzyl alcohols, a wide range of 2,4,6-trisubstituted pyrimidines (TriPym) and 2,4,5,6-tetrasubstituted pyrimidines (TetraPym) were synthesized (119 examples) in isolated yields of up to 93%.
