| abstract |
The invention has an object of safely and simplynpreparing a large amount of a ruthenium metathesisncatalyst, which is used as a catalyst for a carbon-carbonnbond formation using, particularly, a metathesisnreaction. The metathesis catalyst comprises thenfollowing complex composition (A) or (B). Thencomposition (A) comprises (1) RuX 1 2 (arene)(PR 1 R 2 R 3 ) andn(i) R 4 CHX 2 2 , (ii) R 5 C≡CH or (iii) R 4 CHX 2 2 and a reducingnagent. The composition B comprises (4) [RuX 1 2 (arene)] 2 ,n(5) PR 1 R 2 R 3 , (6) (i) R 5 C≡CH or (ii) R 4 CHX 2 2 and anreducing agent. |
