The autoignition of cyclopentane and cyclohexane in a shock tube
Ignition delay times of cyclohexane-oxygen-argon and cyclopentane-oxygen-argon mixtures have been measured in a shock tube, the onset of ignition being detected by OH radical emission.

In this work we developed an electrochemical method for 1,4‐dioxygenated compounds, offering broad scope, functional group compatibility, and diastereoselectivity. Abstract The 1,4‐keto carboxylate scaffold is present in the structure of many biologically relevant compounds.

Vibrational Partition Functions from Bond Order and Populations Relationships
A new computational model is presented that predicts vibrational partition functions using bond orders and populations relationships (QBOP). This model demonstrates that thermochemical energy contributions can be reasonably approximated based on well‐conditioned orbital populations without the need for a costly Hessian calculation.

ROLE OF Mn(TPP)Cl IN THE EPOXIDATION WITH SINGLET OXYGEN [PDF]
Mn(TPP)Cl catalyzes cooxidation of olefin in the singlet oxygenation of sulfid. Mn(TPP)Cl is able to transfer an oxygen atom from a peroxidic intermediate generated in singlet oxygenation of sulfide to a metal ion affording metal 0x0 species which is ...

En Route Toward Sustainable Polycarbonates via Large Cyclic Carbonates
The use of safe carbonylating agents, allowed by a suitable (bio)catalytic systems, affords the sustainable and green synthesis of large‐ring cyclic carbonates by reaction of renewables such as bio‐based diols. These carbonates are prone to ring‐opening polymerization paving the way for the production of circular aliphatic polycarbonates.

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.

Die Synthese von 2,5‐cis‐disubstituierten Tetrahydrofuranen (THFs) und anderen THF‐Derivaten wird über einen retrosynthetischen Ansatz ermöglicht, bei dem aus Acylchloriden erzeugte Acyliumionen mit verschiedenen Alkenen behandelt werden. Ein Ladungsrelokalisierungprozess führt zur Bildung von Oxocarbenium‐Ionen, die zu den gewünschten THF‐Strukturen ...
