Journal of Polymer Science, EarlyView.Eleven allylated sugar frameworks combined with seven dithiol compounds create 77 thiol‐ene networks with a wide range of thermomechanical properties. Analysis based on composition reveals that both the sugar's functionality and the scaffold's structure work in conjunction with dithiol chemistry to influence the rubbery modulus, glass‐transition ...

Flavin Catalysts in Organic Synthesis
Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.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 ...

Direct Allylation of Quinones with Allylboronates
, 2016 Allylboronates undergo C–H allylation of unsubstituted or monosubstituted benzoquinone and naphthoquinone substrates. In the case of 2,5- or 2,6-disubstituted quinones addition involving the substituted carbon takes place.

Aggregate, Volume 7, Issue 11, November 2026.Conformational fixation of donor–acceptor merocyanines modulates excited‐state relaxation and fluorescence. Viscosity‐ and aggregation‐dependent emission, combined with TDDFT calculations, reveal a strongly twisted charge‐separated state in solution and a torsionally constrained emissive state in rigid environments, establishing a unified picture of ...
