Catalysis in flow: Operando study of Pd catalyst speciation and leaching

A custom-made plug flow reactor was designed and constructed to examine the behaviour of Pd catalysts during Suzuki-Miyaura cross-coupling reactions. Spatial-temporal resolution of catalyst activation, deactivation and leaching processes can be obtained by single-pass experiments. Subsequent deployment of the flow reactor in a XAS beam line revealed speciation of Pd along the catalyst bed

Catalysis in Flow: Nickel-Catalyzed Synthesis of Primary Amines from Alcohols and NH₃

A highly selective synthesis of primary amines from alcohols and NH₃ was achieved on using a commercially available Ni catalyst, without adding H₂. Using a continuous flow reaction platform, the amination of aliphatic alcohols can be achieved in good yields and selectivities, as the accumulation of water byproduct can be removed. Competitive formation of the nitrile side-product was suppressed when the catalyst was prereduced. Modes of catalyst deactivation were also briefly examined

Synthesis of P-chirogenic diarylphosphinoacetic acids and their proline derivatives for palladium-catalysed allylic alkylation reactions

The synthesis of P-chirogenic diarylphosphinocarboxylic acids was achieved, from which a new class of amido- and amino -diphosphine ligands (PNP*) were derived, containing an L-proline backbone. The catalytic activities of the novel ligands were evaluated in the palladium-catalysed allylic alkylation reaction of 1,3-diphenylpropenyl acetate
