Binuclear and tetranuclear complexes prepared by reactions of dodecacarbonyltriruthenium with the N-substituted cinnamic acid amides. Crystals and molecular structures of [Ru2(μ-H)(μ-η3-PhCCHC(O)N(CH2)4)(CO)6] and [Ru4(μ3-H)2(μ-η3-PhCCHC(O)N(CH2)4)2(CO)10]
摘要:
The thermal reactions of Ru-3(CO)(12) with the N-substituted cinnamic acid amides PhCH=CHCONRR' (1) in hydrocarbons yield the binuclear and tetranuclear complexes, [Ru-2(mu-H)(mu-eta(3)-PhC=CHC(O)NRR') (CO)(6)] (2) and [Ru-4(mu(3)-H)(2)(mu-eta(3)-PhC=CHC(O) NRR')(CO)(10)] (3), involving five-membered oxaruthenacycles eta(3) coordinated by the second ruthenium atom. The structures of the complexes were determined by single crystal X-ray diffraction studies. On heating in hydrocarbons, complexes 2 are converted into clusters 3. The reverse transformation occurs on treatment of complexes 3 by methylene chloride. (C) 1998 Elsevier Science S.A. All rights reserved.
