Photoinduced Selective Construction of Densely Functionalized Spirocyclic Ethers With Carbyne Equivalents

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
A reactivity programmed cascade between carbyne equivalents and allylic benzoates was developed that sequentially orchestrates all three reactivity modes of carbyne equivalents, enabling the rapid installation of three σ‐bonds at a single carbon center and providing efficient, scalable access to structurally diverse spirocyclic ethers. ABSTRACT Carbyne

Recent Progress in Homogeneous and Heterogeneous Pd Catalyst Systems for Suzuki‐Miyaura Coupling in the Absence of Added Base

ChemCatChem, Volume 18, Issue 9, 14 May 2026.
Suzuki–Miyaura coupling (SMC) is a powerful C─C bond forming method, but stoichiometric bases cause salt byproducts and protodeboronation. Base free SMC overcomes these issues and expands the range of compatible substrates. ABSTRACT Suzuki‐Miyaura coupling reaction (SMC) is an efficient method for constructing C─C bonds.

Acceptorless Dehydrogenative Polymerization

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
Acceptor‐less dehydrogenative polymerization (ADP) enables the atom‐economic step‐growth synthesis of different type of polymers directly from simple alcohols, releasing H2 as the sole by‐product. This review outlines the mechanistic foundations, catalytic systems, and emerging polymer architectures of ADP, highlighting its potential as a sustainable ...

Reversible Dihydrogen Splitting and Diradical Reactivity of 1,4‐Digermabenzene‐1,4‐diide

ChemistryEurope, Volume 4, Issue 5, May 2026.
The diradical reactivity of the 1,4‐digermabenzene‐1,4‐diide, [(ADC)Ge]2, has been demonstrated with a range of substrates. Notably, it undergoes reversible dihydrogen splitting and radical coupling with TEMPO (2,2,6,6‐tetramethylpiperidinyloxyl = RO), forming [(ADC)GeH]2 and [(ADC)Ge(OR)]2, respectively.

Bis(silylene)‐Mediated N═N Bond Scission of Diazo Compounds

Angewandte Chemie, Volume 138, Issue 18, 27 April 2026.
The carborane‐based bis(silylene) enables unprecedented N═N bond scission in diazodiarylmethanes. While xanthene‐ and aniline‐based scaffolds promote end‐on addition with partial N═N activation, the carborane‐based variant uniquely achieves complete N═N bond scission of Ar2C═N═N compounds, resulting in isolable disilicon nitride imino species.

Periodic Influences on the Charge‐Transfer and Radical Ion Pair Formation in Pnictogen‐Based Frustrated Lewis Pairs

ChemistryEurope, Volume 4, Issue 5, May 2026.
Systematic pnictogen variation (P, As, Sb, Bi) in PnMes3–B(C6F5)3 Frustrated Lewis Pairs (FLPs) reveals how both the energy and intensity of charge–transfer excitation can be tuned. Increasing pnictogen–boron orbital overlap and dispersion enhances oscillator strength and encounters complex stability, enabling higher radical ion pair concentrations ...
