Science and a member of KAUST’s Catalysis Research Center, “but hydrogen can be a lot of trouble.” Hydrogen’s troublesome nature lies in the fact that it is explosive and flammable, specifically when used in large quantities. In a recently published paper appearing on the cover and in the March 27 issue of the Journal of the American Chemical Society, Prof. Cavallo and co-authors from the University of St Andrews (UK) and the Universitat de Girona (Spain) examined the difficulties of hydrogenation, isolating a hydridoformatopalladium complex, [Pd{OC(O)H}(H)(IPr)(PCy3)], which can be used to carry out catalytic transfer hydrogenation, a “viable alternative,” the researchers note, to the classical reduction pathway using potentially danger-

supporting research that is not only related to [SABIC’s] business and future plans,” said Mohamed Al-Mady, SABIC Vice Chairman and CEO, “but also relevant to the development and expansion of knowledge for the benefit of humankind.” Al-Mady explained that the funding for the five SABIC Presidential Chair Recipients demonstrates SABIC’s commitment to develop KAUST talent, allowing the assistant professors to research solutions to problems that are not only relevant to SABIC’s long-term strategic goals, but also to the future goals of the Kingdom. “This is an investment allowing both KAUST and SABIC to support Saudi Arabia’s development vision with the prospect of new, disruptive technologies and materials for a more accountable and sustainable future,” he stated. Continued Occhiello: “As we enter into new areas of research and technology, talented faculty at KAUST are seen as a rich source of knowledge that can benefit KAUST, SABIC, and the scientific community at large.” The SABIC Presidential Chair Recipients were quick to note their gratitude for the support. KAUST’s SABIC Presidential Chair Recipients were honored to receive the awards from SABIC. From left to right: Drs. Kuo-Wei (Andy) Huang, Osman Bakr, and Ulrich Stingl.

Prof. Luigi Cavallo and his co-author, KAUST visiting researcher Dr. Albert Poater, discuss computational chemistry at the University.

Through the use of nuclear magnetic resonance (NMR) spectroscopy, the researchers discovered that palladium tricyclohexylphosphine N-heterocyclic carbene complexes can act as tandem catalysts in reaction media, liberating hydrogen from formic acid and then using the hydrogen to hydrogenate the substrates. Tandem catalytic hydrogenation of alkenes and alkynes through the use of formic acid was effectively carried out using the complexes. Prof. Cavallo and Dr. Albert Poater, a KAUST visiting researcher from the Universitat de Girona, performed the computational side of the research to clarify how the catalyst complexes work, with the scientists from St Andrews carrying out the experimental research. “I see computational chemistry as a kind of microscope that can be used to investigate nature, to get information and to get new ideas to move forward, and I very much like to collaborate with the experimentalists,” says

‘Bravo and Hats Off!’ for KAUST’s Sunset and Community Concerts On April 14 and 27, the KAUST community was treated to two “in-house” concerts presented by members of the community. The Community Concert on April 14 featured both the orchestra and the chorus, with the orchestra performing J.S. Bach, W.A. Mozart, several contemporary pieces, and a regional work by Egyptian singer and composer Mohammed Abdel Wahab. The chorus delighted the audience with songs ranging from those based on verse from Carl Sandburg to the Irish melody, “Danny Boy.” “The orchestra and chorus marveled us again,” said Damián San Román Alerigi, a PhD student in the Photonics Laboratory. “It was fantastic to see the members of our community coming together to bring us – even for an hour – wonderful tunes and a joyful time.” Added Daniel Binham, a PhD student in the Geometric Algorithms Group and a member of the chorus, “My favorite moment was [the performance of] ‘Oh Danny Boy, I love you so.’ I felt the same for the concert.” The Sunset Concert on April 27, which was held in the beautiful setting of the University Library, included pieces for piano, guitar, and violin, and featured composers such as Arcangelo Corelli,
