Reactivity of a Methylene‐Bridged 1,3‐Bis(germylene) in Dynamic Equilibrium with Its Dimer

Angewandte Chemie, EarlyView.
We report the properties and reactivity of an unprecedented methylene‐bridged 1,3‐bis(germylene) derivative. In the solid state, the 1,3‐bis(germylene) derivative undergoes dimerization to afford a 1,2,4,5‐tetragermacyclohexa‐1,4‐diene (Ge4CHD) derivative.

Flow behaviors and dynamic recrystallization mechanisms study of TC4 under different temperatures and strain rates

Journal of Materials Research and Technology
The flow behavior of TC4 was studied through thermal compression experiments conducted at deformation temperatures of 910, 930, 950, and 970 °C, and strain rates of 0.01, 0.1, 1, and 10 s−1. After hot deformation, the dynamic recrystallization mechanisms

Oriented for Efficiency: Textured Se Thin Films Fabricated by Vapor Transport Deposition for Emerging Photovoltaic Applications

Advanced Energy and Sustainability Research, EarlyView.
A low‐temperature vapor transport deposition (VTD) method enables controlled crystallographic texture in Se thin films. Higher annealing temperatures promote vertical (003)‐preferred orientation, enhancing film quality and device efficiency. Optimized morphology and orientation yield solar cells with > 4% efficiency under AM1.5 G and up to 10% under ...

Stepwise Acetylene Insertion and Ammonia Activation at a Digallene and Diindene

Angewandte Chemie, EarlyView.
The stepwise insertion of acetylene into the E═E bonds of digallenes and diindenes is reported. This leads to the selective formation of four‐ and six‐membered rings with 2π E2C2 and 4π E2C4 cores. The six‐membered cyclohexadiene analogues are Lewis‐acidic and can form stable, isolable adducts with ammonia, which—upon heating—undergo ammonolysis ...

Enantiopure Chiral Crystals: A Powerful Tool for Absolute Asymmetric Synthesis

Asian Journal of Organic Chemistry, EarlyView.
This review covers absolute asymmetric syntheses, which allow the preparation of enantiomerically enriched chiral compounds from achiral precursors. By exploiting the crystallization of certain compounds as a conglomerate, enantiopure chiral crystals are spontaneously obtained.

Is a Malleable Active Site Loop the Key to High Substrate Promiscuity? Hybrid, Biocatalytic Route to Structurally Diverse Taxoid Side Chains with Remarkable Dual Stereocontrol

Angewandte Chemie, EarlyView.
A highly stereoselective, dynamic reductive kinetic resolution (DYRKR) entry into myriad Taxotere‐like side chains with Clostridium acetobutylicum alcohol dehydrogenase (CaADH) enzyme is reported. Follow‐on cross couplings expand the structural diversity of the library (36 total examples).
