18F‐Radiopharmaceutical Diversification Enabled by Deaminative Cross‐Electrophile Couplings

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
A general Ni‐mediated (C)sp2–(C)sp3 cross‐coupling expedites access to 18F‐radiopharmaceuticals, essential for positron emission tomography imaging and drug discovery. This late‐stage diversification approach was implemented across three user‐friendly automated protocols affording 18F‐radiotracers in sufficient quantities for imaging.

The cranial, mandibular, and hyoid anatomy of softshell turtles (Trionychidae): A revised character list for phylogenetic analysis

The Anatomical Record, EarlyView.
Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...

Pyridinium N-(2'-azinyl)aminides: Regioselective synthesis of 2-alkylaminoazines [PDF]

, 2000
The regioselective alkylation of pyridinium-N-(2'-azinil)aminides with alkyl halides under mild conditions is described. The alkylation, combined with a reduction of the N-N bond, allows an easy preparation of 2-alkylaminoazines.The authors wish to thank

Bis‐Dichlorosilyl Functionalized C4‐Cumulene With Unique Bonding Scenario

Chemistry – A European Journal, EarlyView.
Herein, we report a silylene‐functionalized C4‐cumulene (2) and investigate its bonding scenario employing computational methods such as NBO analysis, AIM, and energy decomposition analysis‐natural orbital for chemical valence (EDA‐NOCV). The EDA‐NOCV analysis showed that compound 2 prefers to possess electron‐sharing covalent sigma and dative covalent

Selective Catalytic Oxidation of Benzyl Alcohol to Benzaldehyde With Alkyl Allyl Carbonates and Pd(II) Allyl‐Amidinate

Helvetica Chimica Acta, EarlyView.
A Pd(II) allyl‐amidinate complex catalyzes the selective oxidation of benzyl alcohols to aldehydes using allyl alkyl carbonates as tailored, mild oxidants. The carbonate reagent acts both as oxidant and in situ base, enabling chemoselective conversion and minimizing overoxidation under mild conditions.

Identification of a mutation in the para-sodium channel gene of the cattle tick Rhipicephalus (Boophilus) microplus associated with resistance to synthetic pyrethroid acaricides [PDF]

, 2009
Resistance against synthetic pyrethroid (SP) products for the control of cattle ticks in Australia was detected in the field in 1984, within a very short time of commercial introduction.
