The Chemical Record, EarlyView.This publication describes how R. B. Woodward and Roald Hoffmann crafted their masterpiece publications. Illustrations include Woodward's first draft of the famous “Violations There are none. Nor can violations be expected of so fundamental a principle of maximum bonding.” Original but discarded text shows the stepwise paths toward the W‐H masterpieces.

A Neutral “Masked” Diborene and Its Reactivity Toward Metal‐Free Pyridine Homocoupling
Angewandte Chemie, Volume 138, Issue 27, 1 July 2026.An unprecedented neutral “masked” diborene, formed via intramolecular arene dearomatization of an N‐heterocyclic imine‐supported free diborene, can be photochemically released to regenerate the highly reactive triplet diborene intermediate. Computational analysis elucidates the bonding situation of the hitherto elusive free diborene species, and the ...

Synthesis and Thermolysis of Ylidyl‐Substituted Stannylenes
Zeitschrift für anorganische und allgemeine Chemie, EarlyView.The synthesis of an amino(ylidyl)stannylene is reported. The title compound was characterized via X‐ray diffraction and features a Sn2C2 heterocycle. Thermal treatment of the stannylene leads to the elimination of the amine. The products of the thermolysis are discussed.

Toward Sustainable Carbonylation Reactions Enabled by CO Surrogates in Green Solvents
ChemSusChem, Volume 19, Issue 13, 14 July 2026.Carbonylation reactions offer a sustainable route to valuable carbonyl compounds. This review highlights methodologies that exploit carbonylative coupling to drastically enhance process sustainability, avoiding the direct use of CO through CO surrogates and promoting syntheses in green solvents potentially derived from renewable and sustainable sources.

Advanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.In this article, we present a new modular approach for the synthesis of bulky monophosphine ligands by nucleophilic addition of Grignard reagents to peri‐phosphine isoindolium salts as stable building blocks. Outcompeting the established catalytic systems (PPh3)AuCl and (XPhos)AuCl, the phosphine gold complexes show high catalytic activity at low ...

Advanced Synthesis &Catalysis, Volume 368, Issue 13, 2 July 2026.Combining dichloro and diiodo ruthenium catalysts produces mixed chloro–iodo species via in situ halide exchange, resulting in a new, more efficient catalytic system. The mixed catalysts outperform their homo‐anionic counterparts, delivering enhanced activity, higher conversion, and strong suppression of isomerization under both thermal and ...
