Outline of Final Research Achievements |
This project was focused on the developments and applications of catalytic alkylation reactions. The significant achievements are as follows. Alkyl-alkyl cross-coupling reactions using Fe, Co, Ni, and Cu along with unsaturated hydrocarbon additives were developed and examined in detail. The Cu catalyst shows quite high catalytic activity, achieving more than 1 million TON. The Co catalyst enables cross-coupling of tertiary alkyl Grignard regents to construct quaternary carbon centers. Site-selective alkylation of 1,3-dienes at the internal carbon was achieved by Cu catalyst. Ni catalyst enables multicomponent coupling reactions of 1,3-butadiene. We succeeded in isolation of anionic Ni complexes, that have been proposed as the key catalytic intermediates in the cross-coupling reactions. Natural products containing a long alkyl chain were synthesized using Ni-catalysts. Another achievement includes development of chemical transformations of less reactive bonds such as C-F, C-O and C-H.
