No full textThe new dialkynylated complexes Ru(eta(6)-DEB-Si)(eta(4)-COD), 4a, Ru(eta(6)-DEBP-Si)(eta(4)-COD), 4b1, Ru-2(eta(6),eta(6)-DEBP)(eta(4)-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(eta(6)-naphthalene)(eta(4)-COD). The complexes Ru(eta(6)-DEB)(eta(4)- COD), 5a, and Ru(eta(6)-DEBP)(eta(4)-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
