Dihalogens Binding and Activation by Imidazoline-2-Chalcogenone Model Derivatives: Insight from a Computational Approach. [PDF]

Chemistry
1,3‐dimethyl‐4‐imidazoline‐2‐chalcogenones react with dihalogens, initially forming a charge‐transfer (CT) adduct, which may evolve to the most stable T‐shaped hypercoordinate (TY) species. However, in silico results show that the CT adduct is more stable than the corresponding TY species for the sulfur and iodine combination.

Kumada-Tamao Catalyst-Transfer Condensation Polymerization of AB₂ Monomer: Synthesis of Well-Defined Hyperbranched Poly(thienylene-phenylene). [PDF]

Macromol Rapid Commun
Kumada‐Tamao catalyst‐transfer condensation polymerization of AB2 monomer in the presence of Ni(dppe)Cl2 in THF affords hyperbranched poly(thienylene‐phenylene) with a narrow molecular weight distribution and controlled molecular weight, which is close to the theoretical molecular weight calculated from the ratio of consumed AB2 monomer to Ni(dppe)Cl2.

Maleic Anhydride and Its Derivatives: A Brief Review of Reactivity and Properties in Radical (Co)Polymerizations. [PDF]

Macromol Rapid Commun
Maleic anhydride (MAnh) and its derivatives are underutilized monomer classes, each with unique reactivities and properties, which afford the synthesis of highly functional (co)polymers. This review explores the current understanding, opportunities, and limitations associated with maleic anhydride and its derivatives in conventional radical and ...

Transition-Metal-Free Synthesis of Unsymmetrical Diaryl Tellurides via S_H2 Reaction of Aryl Radicals on Tellurium

Molecules, 2022
Although diaryl tellurides are parent organotellurium compounds, their synthesis methods, especially for unsymmetrical ones, are limited. This may be due to the instability of diaryl tellurides and their synthesis intermediates under reaction conditions.

Cyclization Reactions Involving 2-Aminoarenetellurols and Derivatives of α,β-Unsaturated Carboxylic Acids

Heteroatom Chemistry, 2021
The reductive cyclization of arenetellurols carrying α,β-unsaturated amide functionalities in the ortho position was investigated. Conceptually, such compounds can form 1,3-tellurazoles without the involvement of the unsaturation in the ring closure ...
