Diaryl Thiourea Catalysts Promote the Formation of Propargyl Enol Ethers in the Claisen Rearrangement Sequence

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The allenyl ketone products of an enol ether formation–propargyl Claisen rearrangement sequence are susceptible to acid‐catalyzed isomerization to yield the corresponding conjugated dienones. A diaryl thiourea catalyst was found to promote the desired reaction sequence while suppressing the competing isomerization.

Optimisation of Electrokinetic Extraction System: Colourimetric Determination of Copper (II) in Sand Using Polymer Inclusion Membrane

open access: yesELECTROPHORESIS, EarlyView.
Electrokinetic extraction (EKE) allows the direct transfer of heavy metals from soli samples, such as soil and sediment, into a polymer inclusion membrane (PIM) with a colourimetric detection. This avoids length and complex sampling handling and extraction processes.
