Group Coordinator: Pedro Teixeira Gomes


IMG_3699The group activities are centred in the areas of Organometallic/Coordination Chemistry and Catalysis, involving: i) the synthesis of new polyfunctional chelating ligands and their coordination to metal centres to produce complexes with specific electronic and stereochemical properties, ii) the study of their molecular structures, using solution NMR, X-ray diffraction and DFT, and iii) experimental reactivity studies, stoichiometric or catalytic, and computational mechanistic calculations, all together providing an integrated vision of the chemical behaviour of the systems. The application of the new metal complexes as catalysts for several organic reactions or as functional materials is an important objective of the group. The most significant current lines of research are outlined below.

1) Metal Complexes for Enantioselective Oxidation Catalysis (sulfoxidation and epoxidation):

a) Molybdenum, tungsten and vanadium diamine bis(phenolate) complexes

b) Molybdenum, tungsten, vanadium and titanium N-heterocyclic carbene complexes

IMG_37102) Early Transition Metal Complexes Based on Dianionic Cyclam Ligands

a) Hydroamination catalysis towards the synthesis of naturally relevant azarings

b) Yttrium complexes with diamido/diamine cyclams as ancillary ligands: syntheses, reactivity and computational studies

c) Catalytic applications of copper complexes anchored by tetraazamacrocycles (Click Chemistry, syntheses of organic azides, oxidation of alcohols)

d) ROP of cyclic esters: PLA incorporating one cyclam ring for drug deliver

e) New antibiotics derived from cyclams

3) Ring-Opening Polymerisation (ROP) of Cyclic Esters with Supported Early Metal Catalysts

4) Synthesis, Characterization and Optimisation of New Nickel(II) and Palladium(II) Complexes Bearing Iminopyrrolyl Chelating Ligands and their Application as Aluminium-Free Catalysts for the Oligo-/Polymerisation of Olefins.

a) Oligo-/polymerisation reactions performed either in organic or in aqueous emulsion media.

b) Immobilization in mesoporous silica and study of their behaviour towards olefin polymerization.

Medium-high pressure polymerization rig5) Synthesis and Characterization of Luminescent Boron Complexes for Optoelectronic Applications.

a) Mono- and polynuclear boron complexes for OLEDs and Sensors

b) Boron complexes with Thermally Activated Delayed Fluorescence (TADF)

6) Controlled Polymerisation of Vinyl Polar Monomers Catalysed by Fe(II/III) and Co(II/III) Complexes.

7) Synthesis and Characterization of α-Diimino Copper Complexes as Catalysts for Alkyne-Azide Cycloaddition and Mediators of Atom Transfer Radical Polymerisation (ATRP)

8) Pentabenzylcyclopentadienyl Complexes of Representative Elements: Syntheses, Structures and Catalytic Applications

9) Cytotoxic and Hydrolytic Studies of Titanium Complexes
