Carbon-rich dinuclear ruthenium bisallenylidene complexes

Reactions of carbon-rich bispropargyl alcohols with the [RuCl(η5-C5H5)(PPh3)2] result in dinuclear ruthenium bisallenylidene complexes [Ru(η5-C5H5)(PPh3)2(CC=)(Ar)(CC)(PPh3)2(η5-C5H5)Ru](PF6)2 (polyaromatic moiety Ar = anthracene, pentacene, bianthracene, indenofluorene).118
