Beyond the Oxo‐Wall: Synthesis and Reactivity of a Six‐Coordinate Formally CoIV‐Oxo Complex
Angewandte Chemie, EarlyView.We present the first example of a six‐coordinate formally Co(IV)‐oxo complex, [Co(TQA)(O)(OH)]+ (1), which exists as an admixture of CoIV‐oxo and CoIII‐oxyl resonance structures. Complex 1 is capable of performing oxygen atom transfer reactions and abstracting moderately strong hydrogen atoms at rates faster than other characterized CoIV‐oxo compounds.

Reactions of Terminal Olefins With Iron Carbenes
Angewandte Chemie, EarlyView.Iron carbenes react with terminal olefins and show productive metathesis or metathesis‐divergent pathways depending on the nature of the olefin. Reactions proceed through 2π + 2π cycloadditions to generate transient metallacyclobutane intermediates that undergo cycloreversion to generate the metathesis product or the metathesis‐divergent β‐hydride ...

Styrene-Acrylate / CNT Nanocomposites: Structure and Selected Exploitation Properties
Styrene–acrylonitrile copolymer (SAN) and multi-walled carbon nanotube (CNT) nanocomposites were prepared by solution casting from aqueous solution. The composites were prepared with different CNT concentrations.

Angewandte Chemie, EarlyView.The use of 1,1,3,3‐tetramethyldisiloxane (TMDSO) and potassium tert‐butoxide enables direct alkylation of weakly acidic carbon–hydrogen bonds with alkyl halides. Experimental and computational studies support the formation of a substrate‐associated hydride‐like base, providing a single‐step alternative to the classical deprotonation and electrophile ...

Bottlebrush Polyolefin Sulfones as Triggerable and Degradable Pressure‐Sensitive Adhesives
Angewandte Chemie, EarlyView.A grafting‐through alternating copolymerization strategy yields poly(norbornene sulfone) bottlebrush polymers with high molar mass. These materials function as additive‐free pressure‐sensitive adhesives. The incorporation of cleavable sulfone units enables rapid breakdown under mild alkaline conditions, providing a pathway toward sustainable, high ...

Angewandte Chemie, EarlyView.1,2‐Aryl migration involving in situ‐generated alkyl iodine(III) species proceeds through a previously unrecognized 1,2‐C/I(III) dyotropic rearrangement. Migratory aryl fluorination, acetoxylation, and alkoxylation of 2‐alkyl‐2‐aryl‐3‐iodopropanoates provide α‐heterofunctionalized products, accompanied by aryl migration from the α‐ to the β‐position ...
