Copper catalyzed cross-coupling reactions of diaryl ditellurides with potassium aryltrifluoroborate salts [PDF]
, 2009 We present here results of the cross-coupling reaction of diaryl ditellurides with potassium aryltrifluoroborate salts using a catalytic amount of Cu(OAc)2 and bypiridine in DMSO/H2O under air atmosphere.

Halogen, Chalcogen, Pnictogen, and Tetrel Bonding in Non‐Covalent Organocatalysis: An Update
Angewandte Chemie International Edition, Volume 63, Issue 31, July 29, 2024.Recent developments on the use of non‐transient non‐covalent interactions based on elements of groups 14–17 in organic synthesis and organocatalysis are discussed. While halogen and chalcogen bonding are now clearly established in this area, applications of pnictogen and particularly tetrel bonding are only starting to emerge.

The Electrochemical Oxidation of Organic Selenides and Selenoxides [PDF]
, 1997 The electrochemical oxidation of alkyl and aryl selenides was investigated in acetonitrile. The oxidation of diphenyl selenide and di(4‐methylphenyl) selenide led primarily to the formation of their respective selenoxides, which were identified by ...

A Novel and General Method for the Formation of S-Aryl, Se-Aryl, and Te-Aryl Phosphorochalcogenoates [PDF]
, 2009 A new and general method for the synthesis of S-, Se-, and Te-aryl phosphorochalcogenoates (chalcogenophosphates) has been developed. S-P, Se-P, and Te-P bonds were formed by the coupling of readily available dialkyl phosphites with diaryl ...

A Highly Sterically Encumbered Boron Lewis Acid Enabled by an Organotellurium‐Based Ligand
Chemistry – A European Journal, Volume 30, Issue 36, June 25, 2024.The new boron Lewis acid B[OTeF3(C6F5)2]3 combines one of the most sterically encumbered boron centres with a Lewis acidity comparable to that of B(C6F5)3. It additionally provides ligand transfer reactivity towards fluoride compounds as shown in the synthesis of an Au(III) complex and a hypervalent iodine species. Abstract Lewis acidic boron compounds

The limits of precision monomer placement in chain growth polymerization [PDF]
, 2016 Precise control over the location of monomers in a polymer chain has been described as the ‘Holy Grail’ of polymer synthesis. Controlled chain growth polymerization techniques have brought this goal closer, allowing the preparation of multiblock ...

Macromolecular Materials and Engineering, Volume 309, Issue 2, February 2024.A perylene diimide derivative is synthesized and used as photoinitiator for atom transfer radical polymerization of methyl methacrylate. Surface‐initiated polymerization confirms the controlled characteristic by exploiting the presence of terminal bromine on the surface of the particles obtained by suspension.
