Acta of the International Symposia on Metal Complexes ISMEC GROUP SERIES Volume: 3 Year: 2013 Symposium Edition: XXIV http://mat520.unime.it/ismecacta/ ISSN: 2239-2459 Acta of the International Symposia on Metal Complexes – ISMEC Acta, Volume 3 ISMEC 2013, June 16 th – 20 th 2013 – Burgos (Spain) Foreword The 2013 edition of the International Symposium on Metal Complexes (ISMEC) proudly continues the tradition of the XXIII Italian-Spanish Congress on Thermodynamics of Metal Complexes, since its origins held alternatively either in Italy or in Spain. This year, the meeting follows the practice adopted in the former edition of broadening the scope of the Synposium by extending the areas of interest as well as the home countries of potential participant researchers, thus having experienced a notable increase in the overall number of contributions and to internationalize the meeting as well with researches coming from 17 different countries. The conference venue of the ISMEC 2013 edition is the “Aula de Romeros” in the “Hospital del Rey”, the main building of the University of Burgos. Starting from 1195, it was erected by the King Alfonso VIII, and the full construction took several decades. Over the centuries, it was devoted mainly to host the Pilgrims Way to Santiago de Compostela, and in the early XX century it was abandoned. Later, it was reconstructed and in 1991 it was devoted again to public service, to be used as the Faculty of Law and Rectorship of the University of Burgos. The program developed by the Organizing Committee has sought to provide the participants with a balanced combination of both scientific and social programs, embodying the enthusiastic support and warm welcome of the city with the reception to all participants by the Lord Mayor. As an innovative proposal, the ISMEC 2013 also offers a Brokerage session, a special time devised as an opportunity for those who wish to offer/receive collaboration to/from other researchers, thus giving way to new joint research programs and new emerging groups in the near future. It is our strongest desire to convert the ISMEC symposium at Burgos into a memorable gathering with plenty of fond memories, one to be remembered for years.

Approved: Dr. Jason Masuda Supervisor Department of Chemistry Date: April 24, 2019 2 Biphenyl substituted Cyclopentadienyl Ligand Complexes by Ketnavi Ramgoolam Abstract The synthesis of biphenyl substituted cyclopentadienyl ligands are described. The synthetic route is accomplished through the reaction of aryl lithium reagents with cobaltocenium salts, followed by oxidation of the intermediate cobalt(I) species to give the corresponding cyclopentadiene. Detailed information on their preparation, structural, and spectroscopic properties are described. A preliminary reaction towards the biphenyl substituted cyclopentadienyl ligand complexes yielding the corresponding alkali metal salt (K) is also described. Its structural and spectroscopic properties are described briefly. March 20, 2019 3 Acknowledgements First of all, I would like to express my most sincere gratitude to my supervisor, Dr. Jason Masuda, for all of his time, efforts, teachings and guidance. Thank you for being a most wonderful and understanding human being. This project helped me in discovering my potential as a chemist and I had plenty of wonderful experiences and opportunities that I personally believe will forever shape and influence my professional life as well as my personal growth.

  • Piano-Stool N-Heterocyclic Carbene Iron Complexes: 2 Synthesis, Reactivity and Catalytic Applications 3
    1 Piano-Stool N-Heterocyclic Carbene Iron Complexes: 2 Synthesis, Reactivity and Catalytic Applications 3 4 Chloe Johnson, Martin Albrecht* 5 6 Department of Chemistry & Biochemistry University of Bern Freiestrasse 3, 3012 Bern 7 (Switzerland) 8 Fax: (+41) 31-6314644; E-mail: [email protected] 9 10 Abstract. This review summarises the advances of N-heterocyclic carbenes (NHCs) as ligands 11 to iron half-sandwich complexes, often referred to as piano-stool complexes because of their 12 structural motif. The review introduces various synthetic routes towards this sub-class of NHC 13 iron-complexes including in particular direct and transmetallation strategies as well as the 14 synthesis of the carbene directly within the iron coordination sphere. Many of these complexes 15 have demonstrated promising reactivity that is relevant to the arenas of catalysis and materials 16 chemistry. In particular, bond activation (e.g. C–H, Si–H, H–H) processes provide exciting 17 new opportunities to exploit these systems for stoichiometric and catalytic transformations. 18 Substantial advances have been achieved specifically in the catalytic reduction of unsaturated 19 substrates, and this topic is emphasised in particular. | downloaded: 27.12.2020 20 https://doi.org/10.7892/boris.105921 21 source: 1 Content 2 1.
