Abstract
Novel ruthenium pi-arene complexes in which the arene ring has 3 or more halogen atoms bound to it are disclosed. These compounds are reacted with phenoxides and thiophenoxides to form ruthenium pi-arene complexes of polyfunctional aromatic ethers and thioethers which are useful as monomers and crosslinking agents.
