Introduction：
Marcel Schlaf is Professor Chemistry of University of Guelph in Canada, Visiting Professor at Peking University and Dalian University of Technology. He also joined the Dalian Institute of Chemical Physics as the Guest Professor.
Prof. Schlaf has finished his post graduate program of Ph. D from University of Toronto. He has post-doctoral training at University of Ottawa (1996) and became Research Associate at Brookhaven National Laboratory (1997).After that, he was appointed Faculty at University of Guelph in 1999, and Full Professor in 2003. His research interests focus on thehomo- and heterogeneous catalysis, selective transformations of carbohydrates and sugar alcohols catalyzed by transition metal complexes; pyrolysis bio-oil upgrading and biomass conversion to fuels and chemicals.
Abstract：
A shift from fossil to renewable carbon resources as the basis of the (petro-) chemical industry will require the development of new catalytic processes that convert highly oxygenated carbohydrates [Cn(H2O)n] from sugars or ligno-cellulose to deoxygenated products that are identical or at least functionally equivalent to petro-chemicals derived from oil, coal and natural gas.This can in principle be achieved through an iterative process in which water is rejected through an acid catalyzed dehydration followed by a metal-catalyzed hydrogenation saturating any C=C and C=O bonds formed in the process, resulting in the net loss of oxygen and overall hydrodeoxygenation of the biomass derived substrates:
With the necessarily aqueous acidic reaction media, the use of homogeneous catalysts may therefore offer distinct advantages for this task. However, the rational design, synthesis, testing and recycling of catalysts poses must be both Br?nsted acid- and water-stable and survive and be active at temperatures that are unprecedented for homogeneously catalyzed reactions.Attempting to address this challenge, a series of ruthenium and iridium complexes has been developed as ionic hydrogenation catalysts and evaluated against sugar derived substrates.
