摘要：
The 'pincer' pyridine-dicarbene and bipyridyl-carbene ruthenium benzylidene complexes, Ru(C-N-C)Cl-2(=CHPh) and Ru(C-N-N)Cl-2(=CHPh), (C-N-C) = 2,6-bis(DiPP-imidazol-2-ylidene)pyridine, (C-N-N) = (DiPP-imidazol-2-ylidene)bipyridine, have been prepared and characterised by spectroscopic and diffraction methods. They exhibit moderate metathesis activity. Non-symmetrical linear tridentate ether-functionalised N-heterocyclic carbene pro-ligands are also described. (c) 2006 Elsevier B.V. All rights reserved.
