Joe speaks at festive RSC Coordination and Organometallic Discussion Group Christmas Meeting

At the annual RSC Coordination and Organometallic Discussion Group Christmas meeting (UCD Dublin), everyone was asked to select an element as the focus of their talk, to celebrate the end of the International Year of the Periodic Table. Joe gave a talk celebrating the versatility of ruthenium complexes. The talk brought together two different project, linked by this transition metal.

  • Joe with his PhD supervisor Thorri and Dawn Barry
  • IYPT presents for attendees

He spoke about the carbohydrate-functionalised Ru-NHC catalysts which were published recently in Dalton Transactions, as well as some Ru(II) coordination complexes (also featuring carbohydrates) which have shown antimicrobial activity (unpublished results, collaboration with Prof Thorri Gunnlaugsson and Dr Ciaran O’Reilly).

It was a very festive meeting, with inorganic chemists from all over Ireland and the UK in attendance – a great chance to catch up with old friends and new.

Joe gives seminar at Maynooth University

  • Dr Montagner, Joe and Dr Fadda

Joe was invited to give a seminar in his alma mater Maynooth University on 6th December 2019. He spoke about his research into luminescence and carbohydrates and how his current project is bringing these together. The presentation was titled: “Sweetness and light: a journey towards diagnostic tools”.

There was some good discussion afterwards with staff and students of the Department of Chemistry, and a lunch with Dr Diego Montagner and Dr Elisa Fadda, to further continue the conversation.

Thanks to Maynooth for their hospitality!

Joe Publications

New publication in Dalton Transactions

I’m delighted to finally publish this work, the first of my research carried out during my Marie Curie Fellowship in University of Bern to come out. A lot of hard work by Erasmus student Pauline went into gathering data behind this manuscript where we asked the question – what impact would incorporating carbohydrates into the structure of a Ruthenium(II)-triazolylidene complex have on its ability to convert a ketone to an alcohol via transfer hydrogenation catalysis.

There were challenges in isolating the desired compound, so it had to be generated in situ, but we were able to assess the activity, and the results were interesting, and can be found in detail here in Dalton Transactions.

To summarise the conclusions: The carbohydrate functionality does impact catalytic activity (transfer hydrogenation of ketones). In complexes with the glucose directly triazolylidene-bound,  turnover rates were substantially higher when compared to more remote carbohydrate functionalisation (i.e. with an ethylene spacer). Both new complexes, however, have reduced activity compared to  unfunctionalised carbene complexes. Insight was also gained into the nature of the catalytic cycle through a substrate scope analysis.
