Benzo[c][1,2,5]Thiadiazole Linkers Enhance the Effectiveness of Cavity‐Containing Supramolecular Photocatalysts

open access: yesChemistry – A European Journal, EarlyView.
Seven novel supramolecular photosensitizers based on benzo[c][1,2,5]thiadiazole (BTZ) tethered to calix[4]arene (C[4]) scaffolds are reported with facile, scalable, and selective syntheses. Their abilities to produce singlet oxygen have been tested through the photo‐oxidation of α‐terpinene.

Ceramidonines, Fused 3,9‐Diazaperylenes, and Related Compounds: From Synthesis to Physicochemical Properties and Evaluation as Inhibitors of PIM Kinases

open access: yesChemistryEurope
Substituted ceramidonines were synthesized by cyclization of 1‐(arylamino)anthraquinones under acidic conditions. These key intermediates were prepared either by copper‐promoted N‐arylation of 1‐aminoanthraquinone with iodoarenes or, more efficiently, by

Impacts of refining Canadian partially upgraded bitumen: Fluid catalytic cracking

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract In this study, we examine the fluid catalytic cracking (FCC) performance of vacuum gas oil (VGO) from partially upgraded bitumen (PUB), a novel refinery feedstock from Canadian bitumen. FCC experiments were conducted in a lab‐scale FCC unit with VGOs from two different PUBs prepared using thermal cracking and solvent deasphalting, along with ...

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

HCo(PMe3)4‐Catalyzed 1,2‐Selective Hydroboration of Quinolines: Access to Isolable N–B and N–H 1,2‐Dihydroquinolines

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Well‐defined cobalt hydride complexes are versatile catalysts. Two key features of HCo(PMe3)4 are that it promotes highly selective 1,2‐hydroboration of quinolines to form N–B‐substituted 1,2‐dihydroquinolines (1,2‐H‐DHQs) under mild conditions, and that its volatile phosphine ligands and high solubility in pentane enable simple purification, allowing ...

Conjugation with Acridines Turns Nuclear Localization Sequence into Highly Active Antimicrobial Peptide

open access: yesEngineering, 2015
The emergence of multidrug-resistant bacteria creates an urgent need for alternative antibiotics with new mechanisms of action. In this study, we synthesized a novel type of antimicrobial agent, Acr3-NLS, by conjugating hydrophobic acridines to the N ...

Single‐Step Generation of β‐Ketosulfides from Epoxides and Thiols Catalyzed by a Ru(II)–Pincer Complex

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
β‐Ketosulfides can be generated in a single step through direct coupling of epoxides and thiols, catalyzed by a Ru(II)–pincer complex. This process requires no substrate preactivation with leaving groups or the use of additives, and liberates H2 gas as a byproduct.

Heteroatom location‐ and orientation mode‐dependent reverse intersystem crossing rate in multiple resonance emitters

open access: yesFlexMat, EarlyView.
By constructing two pairs of isomers with different heteroatom anchoring positions, the relationship between heteroatom location and orientation mode and reverse intersystem crossing rate constant (kRISC) in multiple resonance (MR) emitters is systematically investigated.
