Oxidative Coupling of ?,? - Di(cyclopentadienyl)alkyl-diides

open access: yesCHIMIA, 1991
The CuII-induced oxidative coupling of ?,?-di(cyclopentadienyl)alkyl-diides 6 (n = 2 to 5) – as well as of 1,1,2,2-tetramethyl derivatives 10 and 13 of 6a (n = 2) – has been investigated in view of pertinent questions concerning the 'coupling ...

Second‐Sphere Aromatic Substitutions That Tune H‐Atom Transfer Reactivity Observed for a Series of S = 1 Nonheme FeIV=O Complexes: An Enthalpy‐Entropy Compensation Effect

open access: yesAngewandte Chemie, EarlyView.
A series of oxoiron(IV) complexes was synthesized to determine the impact of electronically tuned aromatic substitution in the secondary sphere of the ligand. Despite possessing identical electronic properties, they show significant differences in C─H oxidation reactions.

Stereoselective Synthesis of Cyclohexanes via an Iridium Catalyzed (5 + 1) Annulation Strategy [PDF]

open access: yes, 2018
An iridium catalyzed method for the synthesis of functionalized cyclohexanes from methyl ketones and 1,5-diols is described. This process operates by two sequential hydrogen borrowing reactions, providing direct access to multisubstituted cyclic products

Phosphine Coordination to Ce, Nd, Np, and Pu in ArBiAMPtBu‐Supported Complexes and Their 2H and 13C Isotopologues

open access: yesAdvanced Science, EarlyView.
A dianionic ligand designed to encourage metal‐phosphine coordination—bis((3,5‐dimethylphenyl)amidomethyl)tertbutylphosphine (ArBiAMPtBu)—was employed in the synthesis of paramagnetic complexes of Ce, Nd, Np, and Pu, producing MI(ArBiAMPtBu)(thf)3.

Spatially Confined/Ligand‐Directed Ultrabright NIR‐AIE Nanoprobe for In Vitro Rapid Detection and In Situ Imaging of Bacterial Septic Arthritis

open access: yesAdvanced Science, EarlyView.
Inorganic PbS quantum dots spatially confine AIEgens and enable cooperative luminescence within a ligand‐directed core–shell–shell nanoassembly, generating ultrabright NIR PPANPs with enhanced fluorescence and photothermal performance. The platform enables 10‐min S.

Supramolecular Cadmium‐Telluride Proteoliposomal Assemblies for Real‐Time Detection of Protein‐Catalyzed Pt(II)‐Complexes Transmembrane Translocation: Cu(I)‐Pumps Are Electrogenic Pt(II)‐Drug Uniporters

open access: yesAngewandte Chemie, EarlyView.
Supramolecular mercaptosuccinic acid‐capped CdTe core‐type quantum dot‐encapsulated proteoliposome assemblies (MSA‐CdTe QD PLs) have been developed to study and unambiguously demonstrate real‐time transporter‐mediated turnover translocation of Pt(II)‐based complexes by transmembrane Cu(I) P‐type ATPase pumps (CopA).

Interfacial Salt Redistribution Enables Rapid Atmospheric Water Harvesting in a Biomimetic Multi‐Layer Hygroscopic Membrane

open access: yesAdvanced Science, EarlyView.
A biomimetic multi‐layer hygroscopic membrane redistributes salt toward an air‐accessible nanofiber interface, enabling rapid interfacial deliquescence while a brush‐like hydrogel promotes efficient liquid transport and storage. By decoupling vapor capture from bulk water storage, the membrane achieves fast sorption kinetics and enables rapid‐cycling ...
