Borylcyclopropanes: Synthetic Strategies and Applications

open access: yesAngewandte Chemie, Volume 138, Issue 37, 7 September 2026.
Borylcyclopropanes (cyclopropanes bearing a boron substituent) sit at the intersection of two privileged frameworks in synthesis. This review provides the first exhaustive survey of their chemistry, spanning metal–carbene, nucleophilic cyclization, radical, hydroboration, and C─H activation routes, and documenting applications in medicinal chemistry ...

Alkylation of Benzene with Ethanol over ZSM-5 Based La–P Catalysts

open access: yesBulletin of Chemical Reaction Engineering & Catalysis
Benzene ethylation in the presence of HZSM-5 zeolites is a promising method for producing ethylbenzene. This study examined the effects of modifying lanthanum and phosphorus as additives to the HZSM-5 catalyst, tested in the temperature range of 300-500 °

Synthesis of linear phenyldodecanes by the alkylation of benzene with 1-dodecene over non-zeolitic catalysts

open access: yes, 2002
Linear alkylbenzenes (LAB) are typically manufactured by the alkylation of benzene and α-olefin, employing HF or AlCl3 as catalyst. LAB are the precursors of linear alkylbenzene sulphonates (LABS) used in a variety of industries.

Bolapolyphiles With Bulky Carbosilane‐Based Lateral Groups—Reticular Design of Liquid Crystalline Pentagonal Honeycombs

open access: yesChemistry – A European Journal, EarlyView.
T‐shaped bolapolyphiles with highly branched carbosilane‐based side‐groups self‐assemble into liquid crystalline honeycombs composed of type‐2 pentagonal prismatic cells and p2gg plane group symmetry. ABSTRACT Periodic pentagon tessellations are rarely observed in self‐assembled molecular systems.

Design and optoelectronic profiling of a semicrystalline thiophene–phenylene copolymer for advanced organic electronics

open access: yesPolymer International, EarlyView.
A new semicrystalline copolymer, PTBT‐3OBu, was synthesized. Intramolecular S···O conformational locks induce high backbone planarity, promoting strong interchain coupling and molecular ordering in thin films, seen in an optical red shift. This synergy between planarity and semicrystalline morphology is promising for photovoltaic and electrochromic ...

Copper(II/III) Redox Couple Enables C─H Methylation via a Radical Mechanism Analogous to SAM Enzymes

open access: yesAngewandte Chemie, Volume 138, Issue 36, 1 September 2026.
Biological C–H methylation proceeds through radical pathways mediated by one‐electron redox cofactors, yet no synthetic model has reproduced this reactivity. Here, we report the first isolable Cu(II/III)–methyl complexes that mediate C–H methylation through hydrogen atom transfer and methyl radical rebound.

Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

open access: yesThe Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

Implementation of Dynamic Simulation to Study the Deviation Consequences Along a Complex Process

open access: yesChemical Engineering Transactions, 2019
The dynamic simulation of a chemical process is carried out to quantify the potential consequences that may arise in response to a deviation propagation. For this purpose, a case study is based on the industrial alkylation of benzene by propene to cumene

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

open access: yesThe Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.
