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

Angewandte Chemie, EarlyView.
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.

A Convenient, Safe, and Atom‐Economical Route to a Large Portfolio of Grubbs‐Type Catalysts for Olefin Metathesis via Four‐Coordinate Ruthenium Alkylidynes

Angewandte Chemie, EarlyView.
It may seem counterintuitive to first target a ruthenium alkylidyne when Grubbs‐type ruthenium carbene complexes are the actual goal. In the end, however, this tactic pays valuable dividends in terms of practicality, atom economy, flexibility as well as safety: the new route provides ready access to a large assortment of catalysts for alkene metathesis

Photocatalytic Cross‐Coupling of Phenols and Heteroaryl Halides With Machine Learning‐Guided Reaction Prediction

Angewandte Chemie, EarlyView.
Photocatalytic cross‐coupling: A redox‐neutral photochemical method enables direct C(sp2)─C(sp2) bond formation between phenols and heteroaryl halides using an organic dye and base. Complementary radical generation allows efficient cross‐coupling in up to 91% yield. Mechanistic studies, DFT, HTE, and machine learning rationalize and predict reactivity,

NiH‐Catalyzed Enantioconvergent α‐Alkenylation of Carbonyl Compounds via Markovnikov Alkyne Hydronickellation

Angewandte Chemie, EarlyView.
A NiH‐catalyzed α‐alkenylation via Markovnikov hydronickellation of alkynes enables convenient access to α‐chrial β‐methylene carbonyl frameworks that are prevalent in biorelevant molecules. High regio‐ and enantioselectivities have been achieved with excellent functional group tolerance and applicability toward complex structures. The β‐methylene unit

Numerical and Mechanical Research on Withdrawal Capacity of Parallel-to-grain Connection Part of Mortise and Loose Tenon Joint for Wooden Furniture

BioResources
The mortise and loose tenon (M<) joint is a form between mortise-and-tenon (M&T) joint and dowel. It combines the advantages of easy processing and high bonding strength and has no requirement for the shape of the tenon shoulder.

Sequential Homo‐ and Hetero‐Coupling of Isocyanide and Carbon Monoxide Mediated by Acyclic Imino(silyl)Silylene

Angewandte Chemie, EarlyView.
We demonstrate the sequential reactions between an imino(hypersilyl)silylene and aryl isocyanide or carbon monoxide as a molecular‐level model of the Fischer–Tropsch process, providing systematic and detailed insight into C–C bond formation during the homologation of C1 building blocks.
