摘要：

Bis(NHC) ruthenium benzylidene complex (H2IMe)(2)(Cl)(2)Ru=CHPh (9) [H2IMe = 1,3-bis(2,6-dimethylphenyl)-4,5-dihydroimidazol-2-ylidene] was synthesized facilely by one-step reaction of (PPh3)(2)(Cl)(2)Ru=CHPh (7) with N-heterocyclic carbene (NHC) H2IMe (6). Complex 9 proved to exhibit remarkable catalytic activity for ring-closing metathesis (RCM) reaction at increased temperature. (c) 2007 Elsevier B.V. All rights reserved.
