Coordination Chemistry of Boron Subphthalocyanine With BINOL Derivatives: Unexpected Oxidation to Oxa[4]Helicene and Properties of the Resulting Axially Coordinated Complexes Containing Oxa[4]Helicene and/or BINOL Derivatives

Chemistry – A European Journal, EarlyView.
Treatment of BINOL with a boron subphthalocyanine derivative resulted in the formation of a complex coordinated to an oxa[4]helicene derivative, which is generated via a ring‐closure reaction of BINOL. In contrast, treatment of the monomethyl ether of 1,1′‐bi‐2‐naphthol (BINOL) afforded the expected axially coordinated complex.

Synthesis and Structures of Novel Chiral Cyclic Hypervalent Iodine(III) Reagents for Metal‐Free Ligand‐Transfer Reactions

Chemistry – A European Journal, EarlyView.
Several new chiral cyclic hypervalent iodine(III) reagents have been synthesized and characterized. Carbon‐based ligands were successfully installed onto the hypervalent iodine centers, giving thus access to novel chiral cyano‐, trifluoromethyl‐ or alkynyl‐bearing λ3‐iodanes.

Benzo[c][1,2,5]Thiadiazole Linkers Enhance the Effectiveness of Cavity‐Containing Supramolecular Photocatalysts

Chemistry – A European Journal, EarlyView.
Seven novel supramolecular photosensitizers based on benzo[c][1,2,5]thiadiazole (BTZ) tethered to calix[4]arene (C[4]) scaffolds are reported with facile, scalable, and selective syntheses. Their abilities to produce singlet oxygen have been tested through the photo‐oxidation of α‐terpinene.

Assessment of Attainable Distances in Proteins by Through‐Space 19F–19F Couplings

Chemistry – A European Journal, EarlyView.
De novo synthesized difluorinated tryptophan analogues are site‐specifically incorporated into Cyclophilin A (CypA). 19F–19F NOESY build‐up experiments are recorded for each labeled protein, and the distances derived from cross‐relaxation rates are compared to reference distances.

Synthesis of Tris(indol‐3‐yl)methanes From Indoles, CO2, and Dimethylphenylsilane With BPh3: Two‐Step Construction of π‐Conjugated Systems

Chemistry – A European Journal, EarlyView.
Tris(indol‐3‐yl)methanes were synthesized from indoles, CO2, and PhMe2SiH in the presence of BPh3 in acetonitrile at 50°C. One product, tris(4‐bromo‐1‐methylindol‐3‐yl)methane, underwent a palladium‐catalyzed cascade reaction for the formation of a novel polycyclic heteroaromatic compound, where the methine C(sp3) atom originating from CO2 was ...
