METAL COMPLEX CONTAINING HETEROCYCLIC CARBENE AS CATALYST FOR CARBON-CARBON BONDING REACTION

摘要

PROBLEM TO BE SOLVED: To easily and economically synthesize a heterocyclic ring type carbene as a catalyst for carbon-carbon boning reaction. SOLUTION: This catalyst contains a complex having the formula, [La Mb Xc ] (A)<-> n (wherein M stands for the same or different elements selected from among Pd, Rh, Ni, Ru, and Co; X is the same or different ligands selected from charged or uncharged unidentate ligands or multidentate ligands bound to a center atom; A for chemical substances equivalent to univalent anions or multi-valent anions; b for natural number from 1 to 3; a for natural number from 1 to 5×b; c zero or natural number from 1 to 4×b; n for zero or natural number from 1 to 6, provided c+n>=0; L is the same or different single-ring monocarbene having 5, 6, or 7 ring-composing atoms and at least one nitrogen atom neighboring carbene-carbon, or dicarbenes constituted of two of such monocarbenes mutually bonded by cross-linking; and the ring-system carbenes do not include imidazole and pyrazole compounds).
