Iridium‐Catalyzed Reductive Deoxygenation of Esters for the Synthesis of Sterically Hindered Ethers
Angewandte Chemie, EarlyView.A general method for accessing sterically hindered ethers via reductive deoxygenation of readily prepared ester starting materials is reported. Employing commercially available and bench‐stable IrCl(CO)(P[OCH(CF3)2]3)2 (1–2 mol%) and tetramethyldisiloxane (TMDS) as reductant, this single‐vessel approach operates under mild conditions and provides a ...

Structural Control of Photoconductivity in a Flexible Titanium‐Organic Framework
Advanced Materials, EarlyView.The concept of flexibility is extended to titanium frameworks and use it to gain control over charge transport. MUV‐35 is a flexible doubly interpenetrated framework that can shrink spontaneously its volume by ≈40% to afford a photoconductive, porous state that is thermodynamically favored by non‐covalent interactions. Abstract The soft nature of Metal‐

Electrochemical Deoxygenative Silylation of Alcohols
Angewandte Chemie, EarlyView.Herein, electroreductive deoxysilylation of benzylic and allylic alcohols is demonstrated. The cathodic transformation proceeds via carbanionic intermediates and can be extended to aldehydes and ketones. Mechanistic studies reveal that the reaction outcome is dependent on the thermodynamics and kinetics for the coupling step in combination with the ...

Adsorption and Separation by Flexible MOFs
Advanced Materials, EarlyView.Flexible metal–organic frameworks (MOFs) present significant potential for gas storage and separation due to their structural dynamic. This review explores the rationale behind the flexible MOFs' enhanced working capacity and separation factors. It also addresses key challenges, including phase transition kinetics, crystal robustness, cycling, shaping,
