Transformative, Iterative or Performative? Conceptualising Patterns of Fossil Fuel Phaseout Leadership

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Global leadership in phasing out fossil fuels is an important new frontier in climate governance, yet remains undertheorised within existing scholarly accounts of climate leadership. In this paper, we argue that ‘phaseout leadership’—climate leadership centred on curtailing fossil fuel supply—is a distinct kind of leadership that dominant ...

Helical Dinaphthothiophenes Reveal the Limits of BN‐Based Optical Tuning

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A BN‐7‐thia[5]helicene and an analogous CC‐7‐thia[5]helicene were prepared in two efficient synthetic routes. Their geometrical structures barely differ, which allows us to judge the influence of the BN substitution on the electronic properties. The formal substitution of carbon–carbon (CC) units by boron–nitrogen (BN) units is an established strategy ...

Axial Chirality Control Through Palladium‐Catalyzed Alkenylation Reactions for the Atroposelective Synthesis of 4‐Arylquinolin‐2‐ones

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Palladium(II)‐catalyzed intramolecular C─H alkenylation of cinnamides allows the atroposelective synthesis of axially chiral 4‐arylquinolones, with the chirality being installed by ring formation. DFT studies have shown that the reaction proceeds by prior activation of the alkene and the enantioselectivity is determined during the β‐hydride elimination

Mo‐Catalyzed Synthesis of 3‐Substituted Quinolines From Nitroarenes and Aldehydes

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A one‐pot Friedländer synthesis of 3‐substituted quinolines from readily available o‐nitrobenzaldehydes and aldehydes or acetals has been developed under dioxomolybdenum(VI) catalysis. Pinacol acts as a benign reductant, enabling in situ nitroarene reduction and annulation without isolation of o‐aminobenzaldehydes and provides access to diverse ...

Improving the Sensitivity in Chiral Analysis by Capillary Electrophoresis

open access: yesELECTROPHORESIS, EarlyView.
Most recent advances for the enhancement of sensitivity in capillary electrophoresis, including off‐line and in‐capillary preconcentration techniques and their combinations, and the use of alternative detection systems to UV–Vis spectrophotometric absorption.
