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

Angewandte Chemie, EarlyView.
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).

Microenvironmental Tuning in Isostructural Conjugated Metal–Organic Frameworks for Superior Photocatalytic H2O2 Generation

Angewandte Chemie, EarlyView.
Two isostructural conjugated‐MOFs (Fe‐Tp and Mn‐Tp) photocatalysts were engineered with nonequivalent microenvironmental redox tuning for hydrogen peroxide production. The manganese analog engages both the oxygen reduction reaction and the water oxidation reaction while suppressing decomposition, delivering 10 487 µmol g−1 h−1 with an apparent quantum ...

Analytical Eco-Scale for assessing the greenness of analytical procedures

TrAC - Trends in Analytical Chemistry, 2012
Abstract We propose the analytical Eco-Scale as a novel comprehensive approach to evaluating the greenness of analytical methodology. It is based on assigning penalty points to parameters of an analytical process that are not in agreement with the ideal green analysis.
