  • Acknowledgements

    First of all I would like to thank Prof. Antoni Riera for not only giving me the opportunity to

    carry out my doctoral thesis in his lab but also to completely transport my life from Ireland to

    beautiful Barcelona. Moving to Barcelona and Catalunya was the best decision I ever made

    in my life and it was your acceptance of me into the lab, Toni which made it possible so thank

    you so much. I want to of course thank my thesis supervisor Prof. Xavier Verdaguer for all

    the guidance, advice and help down through the years. You were available when I wasn’t

    sure what to do or where to go next but I was always granted the freedom and independence

    to investigate and explore as I wished for which I was always very appreciative.

    I want to thank everyone in the lab whoever gave me a hand with whatever bit of chemistry I

    was carrying out or equally as important, whoever made the lab a bit more craic to work in.

    To start off with I’ll have to thank (and of course I want to) the one and only Thierry Achard.

    You really helped me settle in at first, teaching me all about PNSO ligands, phosphines,

    rhodium and of course, for those first few nights out watching champions league with some

    Guinness in the Michael Collins before I knew anybody so thanks for that! I want to thank

    Marc Revés, you were always there to give a few pointers here and there especially in the

    beginning. I’ll thank Pablo my personal Spanish teacher (aunque mi español ha empeorado

    bastante ultimamente ya que lleva mil años en usa el muy berretes). I’ll thank Ana Vazquez,

    she was always there to give a hand, I might have only understood about half of what you

    were saying in the beginning (if that) but I loved hearing it! I’ll say thanks to Núria for being

    the bestest hoodie ever! Thanks to Yi-Ning for your ever-present beaming shining positivity!

    Thanks to Thierry León (what do you think about my... yeah!) for making the lab a wee bit

    more interesting! Thanks to A.. A... Alex for keeping the line in such pristine crystal

    cleanliness at all times! And the dry-box! Thanks to Edgarrrr for all that awesome

    hydrogenation time! I want to thank Cati Ferrer, Jean-Claude and Agustí Lledó for all their

    help. Of course I can’t forget in my thanks the frenchie Helea and hippi Silvia (hey soy Seán

    tio!). I’ll give a nod and a wink to the big Dan man, otherwise known as Super-Dan, the best

    signing Toni ever made! And a big, big thanks to all you guys for helping me with the Spanish

    summary - Núria, Edgar, Silvia, Alex and Álvaro!!!

    I want to give special thanks to Clara Caminal for her kind attention and help, whenever it

    was needed throughout the whole process of the PhD. As well I would thank Patricia Nadal,

  • Maria Rovira and Silvia Aguadé for every bit of help and attention you gave through all the

    bureaucratic intricacies that needed to be solved.

    I would thank the three members of my TAC committee Rodolfo Lavilla, Albert Moyano and

    Guillermo Müller for their help, advice and attention throughout the TAC proceedings. I

    would like to thank everybody from the Mass Spec facility for their work and contribution,

    past and present, Marta Vilaseca, Núria Omeñaca, Claudio Diema, Mar Vilanova and

    Marina Gay. I would give my thanks to everybody in the NMR unit in the Parc Científic and

    in UB for their help and contribution namely, Miguel Feliz, Maria Antònia Molins, Vicky

    Muñoz-Torero and Francisco Cárdenas. I would say thank you to Montse Alcón, Ester and

    Belen from Enantia for all their work on the chiral HPLC separations. Thanks should go

    Eduardo Carmelo Escudero for his work on the X-ray diffraction structures of the complexes

    shown here in this work.

    I would say a big thanks to all the great friends I have made here in the IRB down throughout

    the short few years I’ve spent here, to Peter, to Andrey, to Michael, to Marta, Özgen, Arjen,

    Anna-Iris and Gonzalo (the beer festival organizer!) To every single Brutal/ Soft and fluffy

    Deluxer a heads up and a cheers.

    A big special thank you and a kiss to Kader for all her love. A massive hug to my brothers

    Paddy and James who I miss so much and to all my friends who I wish I could spend more

    time with, Damian, Ross, Brendan, Jamie...and Tommy as well.

    And of course to my lovely Mum and my dear old Dad, this thesis is dedicated to you and you

    alone for you are the main reason it has been possible. Thank you for all your support in

    every sense and all your patience. I owe you everything.
