Amide‐Enabled Reversal of Regioselectivity in Carbonyl‐Substituted Allenes

Advanced Synthesis &Catalysis, Volume 368, Issue 20, 16 October 2026.
A substrate‐embedded secondary amide reverses the inherent regioselectivity of carbonyl‐substituted allenes, enabling rhodium‐catalyzed α‐acyloxylation with carboxylic acids. This redox‐neutral method requires no external oxidants or auxiliary‐type directing groups and tolerates diverse carboxylic acids.

Titanium‐Catalyzed Defluorination of Poly(Vinyl Fluoride) and Poly(Vinylidene Fluoride) Under Friedel–Crafts Conditions

Angewandte Chemie, Volume 138, Issue 42, 12 October 2026.
Cationic titanium sandwich catalysts display exceptional activity in the hydrodefluorination of Csp3─F bonds, in the presence of silanes and aromatic solvents (turnover numbers up to 3000). As a result, they can be used to defluorinate challenging fluoropolymers, such as poly(vinyl fluoride) (PVF) or poly(vinylidene fluoride) (PVDF).

Synthesis and Polymerization of a Lactone Building Block Derived From Cashew Nut Shells

ChemSusChem, Volume 19, Issue 19, 14 October 2026.
Cardanol as a renewable substituted phenol feedstock was selectively transformed into the corresponding cyclohexanone derivative by means of a partial metal‐catalyzed hydrogenation. Subsequent conversion via Baeyer–Villiger oxidation gave a lactone product consisting of a mixture of regioisomers, which has been readily converted into its homopolymer ...
