Pathways to Aromatics in the Catalytic Pyrolysis of a Polyvinylchloride Model Compound Revealed by Operando Photoelectron Photoion Coincidence Spectroscopy

ChemSusChem, EarlyView.
How are aromatics formed during catalytic PVC pyrolysis? By utilizing photoelectron photoion coincidence spectroscopy, the cross‐linking reaction mechanism is unveiled to proceed via butadiene dimerization and trimerization, yielding 5‐ or 6‐membered ring species, which are the precursors for benzene, toluene, and xylenes.

Preplant fumigation for sugar beet nematode on cabbage

California Agriculture, 1971
Preplant fumigation with 1,3-dichloropropene and related chlorinated C3 hydrocarbons and Agel TG-67 significantly increased cabbage yields over the untreated check where the nematode Heterodera schachtii was present in high numbers. Some weed control was

A cautionary tale of basic azo photoswitching in dichloromethane finally explained

Communications Chemistry
Many studies of azobenzene photoswitches are carried out in polar aprotic solvents as a first principles characterization of thermal isomerization. Among the most convenient polar aprotic solvents are chlorinated hydrocarbons, such as DCM.

Modular, Tricomponent, and Concurrent One‐Pot Synthesis of Libraries of γ‐Keto Sulfones and γ‐Keto Phosphine Oxides using Brønsted Acidic Eutectic Mixtures

ChemSusChem, EarlyView.
This study presents a sustainable, metal‐free, one‐pot synthesis of γ‐keto sulfones and phosphine oxides using a ChCl/p‐TSA·H2O eutectic mixture. The method enables regioselective CC and CX bond formation under mild conditions, aligning with Green Chemistry Principles.

Contributions of arid climate and hydrothermal fluid flow on sedimentation in saline‐alkaline lakes: Insight from the Ibar intramontane basin (Southern Serbia)

The Depositional Record, EarlyView.
The article demonstrates that brine was central for the supply of Ca and B to the studied saline lake. The ion transport occurred probably by thermal springs, while contributions from surface waters cannot be excluded. However, the saturation and syndepositional precipitation of Ca borates were initiated by an arid climate through evaporation, while ...
