Activation of carbon dioxide by bicyclic amidines
Activation of the carbon dioxide molecule was achieved using bicyclic amidines (DBU, PMDBD, and DBN). The solution reaction of CO2 with amidines yielded the corresponding zwitterionic complexes through the formation of a N-CO2 bond.

Au(I) Complex With an Abnormal Carbene Ligand Shows Anti‐Kasha Dual Photoluminescence Emission
Incorporation of an abnormal N‐heterocyclic carbene into a heteroleptic linear Au(I) complex induces anti‐Kasha dual emission responsive to biologically relevant phenyl sulfate. ABSTRACT We report the first photoactive linear Au(I) complex with an abnormal N‐heterocyclic carbene (aNHC) ligand, Au(aIm)(Cz).

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 ...

Three-Component Domino Acylation/Trifluoromethylation of Bicyclic Amidines
We herein describe a three-component reaction involving bicyclic amidines such as DBN/DBU, acyl fluorides, and TMSCF3 for access to a novel class of N-acyl trifluoromethylated bicyclic aminals.
