Abstract
The 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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
