- Synthesis of new bulky bis(pyrazolyl)methane carboxylate (heteroscorpionate) ligands and their complexes with iron, manganese and nickel
-
Three new sterically demanding ligands based on the bispyrazolylacetic acid motif have been prepared and complexes with Fe(ii), Fe(iii), Ni(ii) and Mn(ii) have been synthesised and characterised. Single crystal X-ray structures are included for two of the ligands in the protonated form and ten other complexes. Additionally, a new general route to amide derivatives has been established, a range of amide derivatives synthesised and their coordination chemistry investigated. Only one metal complex was synthesised from the amide ligands, and was bound via the hydroxylamine groups in preference to the pyrazole and carboxylate donor set. The Royal Society of Chemistry 2012.

- New mononuclear Pd(II) complexes of sterically hindered bispyrazolylmethanes
-
Three new palladium(II) complexes incorporating the bispyrazolylmethane core have been synthesised and fully characterised in the solution and solid state. Single crystal X-ray studies revealed almost complete blocking of the upper face of the palladium ion by the substituents at the 3- and 5-positions of the pyrazole rings. Preliminary screening of the complexes for palladium(II) mediated catalysis revealed good catalytic activity for the Heck coupling reaction.
