Isolation of Anionic N‐Heterocyclic Olefins and Their Versatile Reactivity

Angewandte Chemie International Edition, EarlyView.
A new synthetic approach to anionic N‐heterocyclic olefins (NHOs) via ligand exchange of metalated ylides/diazomethanes with free carbenes is reported. The anionic NHOs adopt bent structures with delocalized anionic charge, which enables versatile reactivity, including the formation of highly functionalized NHOs, thermal rearrangement to N‐heterocyclic

Flow‐Enabled, Modular Access to α,α‐Difluoromethylene Amines

Angewandte Chemie International Edition, EarlyView.
We report a safe and scalable flow‐based strategy for the on‐demand generation of NCF2R anions using a packed‐bed microreactor containing CsF. This protocol enables the late‐stage installation of the CF2 group under mild conditions leveraging three points of diversification, allowing efficient access to a broad range of NCF2R scaffolds.

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

The Anatomical Record, EarlyView.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...
