〔Commemorative Lectures〕
＜“2011 Mitsui Chemicals Catalysis Science Award” 1＞
Photoredox Catalysis and Accelerated Serendipity
Prof. David W. C. MacMillan (Princeton University, U.S.A.)
Prof. MacMillan has made a great contribution to the field of organocatalysis. He has realized a number of asymmetric reactions using organocatalysts having a chiral imidazolidinone framework (the MacMillan’s catalyst). Recently, he has developed a novel activation methodology of substrates via a radical mechanism (SOMO-Activation) which uses chiral organocatalysts in combination with the one-electron oxidant. Furthermore, he has expanded this concept to organocatalytic photoredox reactions using a ruthenium complex as a photoredox agent.
In the lecture, the development of SOMO and photoredox catalysis as well as an introduction to accelerated serendipity were given.

Development of Highly Active Heterogeneous Catalysts Based on the Properties of Metal Hydroxides
Associate Prof. Kazuya Yamaguchi (The University of Tokyo, Japan)
Associate Prof. Yamaguchi has developed highly active heterogeneous catalysts based on the concept of “concerted activation” using metal hydroxides which have both Lewis acid sites and Brønsted base sites. Concretely, he has developed catalysts upon which ruthenium hydroxide is monomerically dispersed for the oxidation of various kinds of alcohols. Besides alcohol oxidation, he has revealed that these catalysts can promote other transformations including hydrogen transfer reactions and hydrations.
In the lecture, concepts for developing highly active heterogeneous catalysts based on the properties of metal hydroxides and the use of these for green functional transformation were given.

Unsaturated Alcohols as Surrogates of Organometallic Reagents in Palladium–Catalyzed C–C Bond Formation
Associate Prof. Hideki Yorimitsu (Kyoto University)
Associate Prof. Yorimitsu has investigated novel palladium-catalyzed C-C bond formations and has found that homoallyic alcohols act as allylic metal equivalents via retro-allylation in the allylation of aryl halides. His strategy uses the properties of neutral molecules and realizes universally regio- and stereoselective allylations which have been difficult to achieve with conventional cross-coupling reactions. Moreover, he has developed a new methodology for constructing heterocycles like epoxides using the palladium-catalyzed cyclization of allylic alcohols with aryl halides.
In the lecture, descriptions of these two reactions including the reaction mechanisms that can realize high selectivities were given.
