Synthesis, Solubilization, and Photophysical Properties of Polyfluorinated Pentacene Dimers

Journal of Physical Organic Chemistry, Volume 39, Issue 7, July 2026.
The synthesis and photophysical analysis of polyfunctionalized pentacene dimers is described. Polyfluorination is employed to modulate the polarizability and to investigate the effects on the mechanism of singlet fission (SF). ABSTRACT A polyfluorinated pentacene dimer, linked with a 1,3‐diethynylphenylene spacer, was synthesized to investigate the ...

Remarkable Formation of Indene Derivatives Upon Friedel–Crafts Acylation Reactions

European Journal of Organic Chemistry, Volume 29, Issue 23, 16 June 2026.
This shows indene derivatives. Under the reaction conditions of a Friedel–Crafts acylation, alkyl benzenes underwent an unprecedented cyclopentannulation furnishing indene derivatives. Alkylbenzene derivatives react with two equivalents of pivaloyl chloride (PivCl) in the presence of aluminum trichloride under formation of indene derivatives with up to

Anaerobic Degradation of Chlorinated Hydrocarbons in Groundwater Aquifers or "Chlorinated Hydrocarbon Degradation"

, 1997
Groundwater contamination by chlorinated hydrocarbons, such as tetrachloroethene (PCE) or trichloroethene (TCE), is a major concern throughout the United States. A developing strategy for the remediation of PCE and TCE contaminated aquifers is anaerobic biodegradation.

MnCl2‐Catalyzed Photochemical Functionalization of Unactivated C(sp3)H Bonds

ChemSusChem, Volume 19, Issue 11, 15 June 2026.
A photochemical method enables the activation of alkanes, utilizing cheap and abundant MnCl2 as the photocatalyst. Alkenylation and alkylation reactions are performed, affording the desired products in good yields. Activation of inert C(sp3)H bonds is of great importance in organic synthesis, since it can functionalize unreactive molecules, such as ...

Processability and Crosslink Density: Role of Peptizers in Natural Rubber and Chlorobutyl Rubber

Journal of Applied Polymer Science, Volume 143, Issue 22, June 10, 2026.
This work evaluates how chemical and physical peptizers affect mastication, vulcanization behavior, and network formation in natural rubber and chlorobutyl rubber. Size‐exclusion chromatography, rheometry, DSC, and swelling analyses demonstrate improved processability but reduced crosslink density with peptizer addition.

Emerging Trends in Organic Photoreactions Utilizing Disulfides

European Journal of Organic Chemistry, Volume 29, Issue 21, 4 June 2026.
Disulfides are versatile, nontoxic alternatives to metal photocatalysts. This review explores their role as photoactivated thiyl‐radical precursors and bifunctional catalysts (HAT/electron shuttling) in diverse transformations. Strategies for electronic tuning and development into recyclable heterogeneous materials are highlighted for sustainable ...
