Cross-Dimerization of Alkenes: One of the major focuses in our lab is the selective cross-dimerization of substituted alkenes by zero-valent ruthenium complex. We have developed the first enantioselecive crossdimerization between substituted alkenes, that goes through an oxidative coupling mechanism. (Org. Lett., 2013, 15, 2486) 2. Bond Activation by Internal Electrophilic Substitution Mechanism: Interal Electrophilic Substitution (IES) mechanism, which is also named as Concerted Metallation Deprotonation (CMD) or Ambiphilic Metal-Ligand Activation (AMLA), is one of the current topics in bond activation processes. However, the understanding in the molecular level and the application is still limited. We have shown multiple C-H bond activation processes of alkyl group in the ortho position of the aryloxo group. (Organometallics, 2014, 33, 1235) 互換性や機能性、使い やすさの向上 2 Research Interests: 3. Successive C-O/C-H Bond Activation of Esters: The C-H bond activation by the Internal Electrophilic Substitution (IES) mechanism normally starts from the oxidative addition of organic halide to the low valent metal compound followed by the anion exchange between the resulting halido and carboxylato (or carbonato) to give (carboxylate)(organo)metal species. If we can make this species directly from esters by the C-O bond activation, this process must be very attractive from the atom and step economy point of view. We have succeeded direct formation of fluorene by the C-O/C-H bond activation process by a Pd catalyst. (Organometallics, 2014, 33, 1921) 4. Highly Active Catalyst for Hydrometallation: We recently found the mono-phosphine Pd(0) compounds to be a highly active hydrometallation catalyst under mild conditions. Hydrometallations, particularly those using main group elements, are highly attractive for the synthetic point of view. 3 Research Interests: The MOLCAT The molcat is a research team headed by Masafumi Hirano at Tokyo University of A & T.
