| Research Abstract |
Clarification of detailed concerted mechanism in the catalytic cross-coupling reactions of aryl halides using monovalent dinickel(I) complex bearing N-heterocyclic carbene, and development of versatile catalytic process have been achieved. (1) First, dinickel(I) intermediary compounds were isolated and determined, and EXAFS and XANES spectra were recorded to determine the structure of them. (1) Mechanistic consideration revealed that a redox cycle between Ni(I)-Ni(I) and Ni(II)-Ni(II) is possible during the catalytic reactions. (2) Buchwald-Hartwig amination of aryl halides with less reactive biarylamines proceeds even at room temperature. (3) Stable and reactive catalyst precursors of nickel(I) are prepared.
