Iridium-Catalyzed Regiodivergent Atroposelective C–H Alkylation of Heterobiaryls with Alkenes
The atroposelective direct C–H alkylation of heterobiaryls with simple alkenes represents a challenging and underexplored frontier. Herein we report an iridium(I)-catalyzed regiodivergent and enantioselective C–H alkylation of 1-arylisoquinolines or 2 ...

Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2
Advanced Functional Materials, EarlyView.High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.

Iridium-Catalyzed Regioselective Hydroalkynylation of Internal Alkenes Directed by an Oxime
, 2021 We report here an iridium-catalyzed hydroalkynylation of allylic alcohols protected by an oxime group. Catalytic alkynylation occurs exclusively at the distal position of the alkene.

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite
Advanced Functional Materials, EarlyView.The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Iridium-Catalyzed 1,3-Rearrangement of Allylic Ethers
, 2023 The 1,3-rearrangement of allylic derivatives has rarely been reported, except for allylic alcohols. Herein, we describe an iridium-catalyzed 1,3-rearrangement of readily available allylic ethers to access the difficultly prepared allylic ethers with a ...
