Chemistry of Tetradentate [C,N : C,N] Iminophosphorane Palladacycles: Preparation, Reactivity and Theoretical Calculations

open access: yesChemistryOpen, 2020
A theoretical and experimental study of tetradentate [C,N : C,N] iminophosphorane palladacycles was carried out for the purpose of elucidating their behavior as compared to the parent Schiff base analogues to determine the prospect of encountering new A ...

A facile route to synthesize cubic gauche polymeric nitrogen [PDF]

open access: yesScience Bulletin, 69(24):3812 (2024)
In this work, the long-sought cg-N with N-N single bond has been synthesized for the first time by a thermal-driven-only chemical route at ambient conditions. The successful synthesis of cg-N was achieved by first creating a solution of azides, which was then pretreated under vacuum conditions.

Radical azidation reactions and their application in the synthesis of alkaloids [PDF]

open access: yes, 2017
Recent advances in radical azidation using sulfonyl azides are presented. For instance, radical carboazidation using α-iodoketones, desulfitative carboazidation, and anti-Markovnikov hydroazidation of alkenes are described. These novel methods tolerate a

Influence of infection on malaria-specific antibody dynamics in a cohort exposed to intense malaria transmission in northern Uganda.

open access: yes, 2013
The role of submicroscopic infections in modulating malaria antibody responses is poorly understood and requires longitudinal studies. A cohort of 249 children ≤5 years of age, 126 children between 6 and 10 years and 134 adults ≥20 years was recruited in

Umpolung Synthesis of Pyridyl Ethers by BiV‐Mediated O‐Arylation of Pyridones

open access: yesAngewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022
We demonstrate that sterically‐ and electronically‐diverse pyridyl ethers can be accessed via BiV‐mediated C−O coupling of 2‐ or 4‐pyridones with arylboronic acids. Use of a bismacyclic reagent not only confers modularity on our methodology, but also results in highly regioselective O‐arylation that is unprecedented for BiV.

Harnessing Synergistic Cooperation of Neighboring Active Motifs in Heterogeneous Catalysts for Enhanced Catalytic Performance

open access: yesAdvanced Materials, EarlyView.
This review examines the critical role of neighboring active motifs in heterogeneous catalysts, emphasizing how their synergistic cooperativity can be rationally designed to modulate catalytic properties. The discussion centers on the modulation of electronic and geometric structures, categorizing the catalytic systems into metal‐acid (Brønsted/Lewis ...

A Photonastic Prototissue Capable of Photo‐Mechano‐Chemical Transduction

open access: yesAdvanced Materials, EarlyView.
Mimicking energy transduction in prototissue assemblies remains a challenge of bottom‐up synthetic biology. In this work, prototissues integrating protocells with photothermal gold nanoparticle proto‐organelles and a thermoresponsive polymeric proto‐cortex are developed.
