Sulfonium, selenonium, telluronium, and iodonium cyanoborohydrides have been synthesized, isolated, fully characterized by various methods, including single-crystal X-ray diffraction (XRD) analysis. The quantum theory of atoms in molecules' analysis based on the XRD data indicated that hydride···σ-hole short contacts observed crystal structures each compound a purely noncovalent nature. telluronium provide significantly higher rate model reaction imine hydrogenation compared with sodium tetrabutylammonium cyanoborohydrides. Based NMR high-resolution electrospray ionization mass spectrometry indicating progress is accompanied cation reduction, mechanism involving intermediate formation elusive onium hydrides has proposed as an alternative to conventional electrophilic activation moiety its ligation cation's σ-hole.

The Groebke–Blackburn–Bienaymé (GBB) three-component reaction, discovered in 1998, is a very efficient strategy to assemble imidazo[1,2- ]-heterocycles starting from amidines, aldehydes and isocyanides. This review aims exhaustively describe innovative aspects of this reaction achieved during the last five years, classifies them into categories: synthetic methods, building blocks, scaffolds, biological activities physical properties.

Abstract Sulfonium, selenonium, telluronium triflates, as well chloronium, bromonium, and iodonium triflates have been examined in the model Schiff condensation chalcogen‐ halogen bond donating organocatalysts, respectively. The kinetic data indicated that catalytic effect of salt is provided via decrease enthalpy activation reaction, whereas – unexpectedly caused by value entropy activation. In addition, it was experimentally shown activity sulfonium selenonium salts significantly lower than chloronium bromonium salts, but latter pair species less stable under reaction conditions former pair.
