摘要：

Reactions of the cyclohexadienyl ruthenium complex [(eta(5)-C6H3Me4)Ru(C10H8)](+) (1) with 2-electron ligands L lead to replacement of the naphthalene ligand with formation of the half sandwich complexes [(eta(5)-C6H3Me4)RuL3](+) (L = MeCN, (BuNC)-Bu-t, P(OEt)(3), 1,3,5-triaza-7-phosphaadamantane). Similar reactions with P(OMe)3 or dppe in the presence of Cl- give the neutral complexes (115-C6H3Me4)Ru(P(OMe)3)2CI or (115-C(6)1-1(3)Me(4))Ru(dppe)CI, respectively. Cation 1 also exchanges the naphthalene ligand for other arenes producing the corresponding sandwich compounds [(115-C6H3Me4)Ru(arene)1+ (arene = C6H6, 1,4C6H4(0Me)2). Complex 1 catalyzes cyclotrimerization of N,N-di(propargyl)tosylamide with 1-octyne or 4-pentynol, but less effectively than [CpRu(C10H8)1. The mechanism of the naphthalene replacement in 1 was studied by DFT calculations. (C) 2015 Elsevier By. All rights reserved.
