Chemistry &Biodiversity, EarlyView.ABSTRACT The plant essential oils (EOs) play a fundamental role in the adaptation to different habitats and environmental conditions. To verify the influence of these factors on the EO of Artemisia absinthium L., we conducted a pharmacognostic study on this species, collected during both the vegetative (V) and flowering (F) stages, in two different ...

Ru‐Catalyzed Alkene Hydrophosphination: Correlating Substrate Scope with An Outer‐Sphere Mechanism
ChemCatChem, EarlyView.The rate of this outer‐sphere hydrophosphination catalyzed by a Cp*Ru complexdepends on the speed of either conjugate addition A delicate balance between these two possible turnover‐limiting steps is sensitive to the structure and electronic character of both the alkene and phosphine substrates, with big impacts on activity and selectivity.

Electrochemical Three‐component Synthesis of Alkenesulfonates from Cinnamic Acids, SO2, and Alcohols
ChemSusChem, EarlyView.An electrochemical three‐component synthesis of alkyl alkenesulfonates from cinnamic acids, SO2, and alkyl alcohols is reported. This metal‐free process employs inexpensive and readily available graphite electrodes in combination with easy‐to‐use stock solutions of SO2 and enables a straightforward decarboxylative preparation of styrene sulfonates via ...
