The new dialkynylated complexes Ru(η6-DEB-Si)(η4-COD), 4a, Ru(η6-DEBP-Si)(η4-COD), 4b1, Ru2(η6,η6-DEBP)(η4-COD)2, 4b2 [COD = 1,5-cyclooctadiene; DEB-Si = 1,4-bis(trimethylsilylethynyl)benzene; DEBP-Si = 4,4′-bis(trimethylsilylethynyl)biphenyl] have been synthesized by the arene exchange reaction with the complex Ru(η6-naphthalene)(η4-COD). The complexes Ru(η6-DEB)(η4-COD), 5a, and Ru(η6-DEBP)(η4-COD), 5b1, have been prepared by desilylation of the corresponding compounds 4a and 4b1. All the complexes have been fully characterized by means of spectroscopic techniques.
The novel dialkynylated complexes Ru(η6-arene)(η4-COD) [arene = 1,4-diethynylbenzene and 4,4′-bis(ethynyl)biphenyl; COD = cycloocta-1,5-diene] have been prepared in high yield by desilylation of the corresponding Ru[η6-(trimethylsilyl)arene](η4-COD) derivatives obtained by the arene exchange reaction with the compound Ru(η6-naphthalene)(η4-COD).Figure optionsDownload as PowerPoint slide
