A rapid and efficient protocol for the synthesis of 2‐benzylbenzaldehydes and anthracenes is reported, based on the infrared (IR) irradiation‐assisted Pd‐catalyzed C(sp3)─H arylation and the tandem C(sp3)─H arylation/electrophilic aromatic cyclization of ortho‐tolualdehydes with aryl iodides via a transient directing group (TGD) strategy.

A Meisenheimer complex derived from two‐fold reduction and protonation of naphthalene monoamide has been identified as a strong organic hydride donor which is able to reduce CO2. ABSTRACT Selective CO2 reduction to formate is challenging due to similar thermodynamics for the reaction to other products such as carbon monoxide and molecular hydrogen ...

Tandem Duplication-Driven Neofunctionalization of UDP-Glycosyltransferases Shapes the Diversification of Triterpenoid Saponins in the Cucurbitaceae. [PDF]
We present a chromosome‐level genome assembly of Siraitia grosvenorii and, through comparative genomics, uncover a conserved UGT73 tandem array driving triterpenoid saponin diversification in Cucurbitaceae. Crystalized SgUGT73AM30 further reveals the regioselectivity mechanism underlying its catalytic activity.

ABSTRACT Public organisations often experience a discrepancy between improvements in technical efficiency and stakeholders' perceptions of integrity and performance. This study analyses the mechanisms that may underlie this efficiency–perception discrepancy in Spanish Defence Delegations during 2020–2023.

ABSTRACT The construction sector is a major contributor to the climate crisis, accounting for over one‐third of global energy‐related CO2 emissions. In response, the European Commission identified the circular economy as a means of achieving green growth and prioritized the construction sector in its Circular Economy Action Plan.

π‐Extended Silyl Enolates as Emerging Platforms in Radical Chemistry
This review covers the emerging role of π‐extended silyl polyenol ethers in radical chemistry. It highlights their versatile roles as electron‐rich SOMOphiles, silyl radical cation precursors, and nucleophilic partners in radical–polar crossover manifolds, while considering recent advances in photoredox catalysis, electrochemistry, and transition metal‐
