1,1‐and 1,2‐Diborylalkenes: Preparation and Synthetic Applications

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 12, 17 June 2026.
In this review, we highlight recent advances in the synthesis and reactivity of 1,1‐diborylalkenes and 1,2‐diborylalkenes, along with various transformations leading to C‐C, C‐heteroatom, and multicomponent products. By providing a comprehensive and practical resource, this review aims to assist researchers in exploring the synthetic utility of 1,1 and

Redox‐Active Guanidines

open access: yesChemElectroChem, Volume 13, Issue 12, 17 June 2026.
Redox‐active guanidines, comprising guanidino‐functionalized aromatics (GFAs) and redox‐active urea azines (RAAs), are electron donors and strong Lewis and Brønsted bases that are used in several applications. They act as redox‐active ligands in bistable coordination compounds and as reagents in dehydrogenative coupling reactions and proton‐coupled ...

From Citrus to Cymene: Understanding the Hydrothermal Conversion of Limonene

open access: yesChemSusChem, Volume 19, Issue 11, 15 June 2026.
When life gives you limonene… Hydrothermal conversion and pyrolysis of limonene give two distinct sets of products, arising from differing reaction cascades. While p‐cymene dominates in the presence of water, indicative of an isomerisation/aromatisation pathway, pyrolysis favours cracking and loss of carbon affording an m‐xylene rich aromatic mix.

Photocatalytic Vanadium‐Mediated Amination of Benzene With Hydroxylamine

open access: yesChemistry – A European Journal, Volume 32, Issue 22, 9 June 2026.
Photochemical activation of N‐phenylphenothiazine (PPT) enables a selective direct benzene amination with hydroxylamine in the presence of various vanadium catalysts under mild reaction conditions. Spectroscopic and kinetic analyses identify a key vanadium(IV)‐hydroxylamine intermediate, elucidate the crucial roles of the acidic medium, the ...

Boron‐Doping of a Macrocyclic Tetrafuran Framework Unveils an Expanded Porphyrinoid With Switchable (Anti)Aromaticity and Conformational Dynamics

open access: yesAngewandte Chemie, Volume 138, Issue 23, 1 June 2026.
We disclose a novel boron macrocycle derived from the sustainable furan building block. The boraporphyrinoid exhibits a global antiaromatic ring current and dynamic conformational flexibility. Twofold reduction induces a switch to strong global aromaticity, accompanied by stiffening of the porphyrinoid backbone.

Toward Larger Cyclo‐9,10‐Anthryleneparaphenylenes

open access: yesChemistry – A European Journal, Volume 32, Issue 22, 9 June 2026.
During a macrocyclization with a dihydroanthracene diol as corner unit, larger oligomers than the trimer and tetramer were formed and isolated up to the nonamer. Their three‐dimensional structures were studied by X‐ray diffraction. The most abundant macrocycles were rearomatized to the corresponding CPP derivatives.
