Cobalt Single‐Atom‐Bonded Covalent Heptazine Framework Selectively Generates Nonradicals in Fenton‐Like Catalysis for Rapidly Purifying Organic Wastewater

EcoEnergy, EarlyView.
Cobalt single‐atom‐bonded covalent heptazine framework activates peroxymonosulfate to generate 1O2, with the concurrent formation of CoO2+, for wastewater treatment. ABSTRACT Engineering the coordination architecture of cobalt single‐atom catalysts (Co‐SACs) represents a promising strategy to activate peroxymonosulfate (PMS) for sewage purification. In

Synthesis of highly substituted allenylsilanes by alkylidenation of silylketenes [PDF]

, 2005
BACKGROUND: Allenylsilanes are useful intermediates in organic synthesis. An attractive, convergent but little used approach for their synthesis is the alkylidenation of stable silylketenes.

Synthesis of Novel BINOL Analogs: 3,3′‐Dicarbonyl‐1,1′‐binaphthyl‐4,4′‐diols as Precursors to the Uncharted 5,5′‐Binaphtho[2,1‐d]isoxazole

European Journal of Organic Chemistry, EarlyView.
The parent 5,5′‐binaphtho[2,1‐d]isoxazole and its 3,3′‐dimethyl and 3,3′‐diphenyl derivatives are synthesized via condensation of the respective dicarbonyl compounds with hydroxylamine, followed by cyclodehydration of the resulting dioximes. The dicarbonyl precursors are obtained through 4‐ or 6‐step sequences from 1‐naphthol or 1‐naphthaldehyde ...

Deep Eutectic Solvents: The Organic Reaction Medium of the Century [PDF]

, 2016
This microreview summarizes the use of deep eutectic solvents (DESs) and related melts in organic synthesis. Solvents of this type combine the great advantages of other proposed environmentally benign alternative solvents, such as low toxicity, high ...

A “One‐Pot” Metal‐Free Synthesis and Evaluation of Antiproliferative Activity of Diversely Functionalized Pyrrolidine‐2‐Ones

Journal of Heterocyclic Chemistry, EarlyView.
A new “one‐pot” metal‐free stereoselective method for the synthesis of novel diversely functionalized pyrrolidine‐2‐ones from N‐alkyl‐ or N‐arylsulfonamidoacetophenones was developed. The majority of obtained compounds possess low micromolar antiproliferative activities.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.
