报告人简介：

Kazushi Mashima received his PhD degree (1986) from Osaka University. He became an Assistant Professor at Institute for Molecular Science, Okazaki National Institutes in 1983 before getting his PhD degree. He moved to Faculty of Engineering, Kyoto University as an Assistant Professor in 1989, and then to Faculty of Science, Osaka University as an Assistant Professor in 1991. He worked as a post-doctoral fellowship with Professor M. A. Bennett, Australian National University in 1992 and as an Alexander von Humboldt fellow with Professor W. A. Herrmann, Technisch Universität München in 1993. He was promoted to an Associate Professor at Faculty (now Graduate School) of Engineering Science, Osaka University in 1994, and then to a full Professor at Graduate School of Engineering Science, Osaka University in 2003. He received Progress Award in Synthetic Organic Chemistry, Japan in 1994, BCSJ Award in 2000, The Chemical Society of Japan Award for Creative Work for 2008, The 9th Green and Sustainable Chemistry Award in 2010, and The Award of the Society of Polymer Science, Japan in 2010. 

讲座摘要：

We found that in situ generated cerium(IV)carboxylate generated by mixing the precursor Ce(OtBu)4withthe corresponding carboxylic acids served as efficient photocatalystsfor the direct formation of carboxyl radicals from carboxylic acidsunder blue light-emitting diodes (blue LEDs) irradiation and air,resulting in catalytic decarboxylative oxygenation of aliphaticcarboxylic acids to give C−O bond-forming products such asaldehydes and ketones. Herein, we also report that tetranuclear complexes including cerium atom work as catalyst for oxidation and alternative copolymerization of carbon dioxide and epoxides.
