Ability of Lewis Acids with Shallow σ-Holes to Engage in Chalcogen Bonds in Different Environments [PDF]
Molecules, 2021 Molecules of the type XYT = Ch (T = C, Si, Ge; Ch = S, Se; X,Y = H, CH3, Cl, Br, I) contain a σ-hole along the T = Ch bond extension. This hole can engage with the N lone pair of NCH and NCCH3 so as to form a chalcogen bond.

Hybrid chalcogen bonds in prodrug nanoassemblies provides dual redox-responsivity in the tumor microenvironment [PDF]
Nature Communications, 2022 While homodimeric prodrug assemblies can improve drug loading and limit toxicity in cancer therapy, bioactivation within the target site is limited. Here, the authors introduce a hybrid chalcogen bond linker to a docetaxel dimeric prodrug nanoassembly ...

Catalysis with Pnictogen, Chalcogen, and Halogen Bonds [PDF]
Angewandte Chemie - International Edition, 2018 AbstractHalogen‐ and chalcogen‐based σ‐hole interactions have recently received increased interest in non‐covalent organocatalysis. However, the closely related pnictogen bonds have been neglected. In this study, we introduce conceptually simple, neutral, and monodentate pnictogen‐bonding catalysts. Solution and in silico binding studies, together with
