摘要：

Treatment of the spiked cluster [Ru-4(CO)(13)(mu-H)(2)(mu(4)-PCF3)] with [Au(PMe3)Cl] in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) results in deprotonation and metal core rearrangement from spiked to butterfly, yielding the heterometallic cluster [Au2Ru4(CO)(12)(mu(4)-PCF3)(PMe3)(2)] 1. Reaction of the open chain cluster [Ru-4(CO)(12)(mu-H)(2)(mu(3)-PCF3)(2)] with [Au(PPh3)Cl] under similar conditions gives [Au2Ru4(CO)(12)(mu(3)-PCF3)(2)(PPh3)(2)] 2 where the hydrides are simply replaced by AuPPh3 fragments. Clusters 1 and 2 are characterised by spectroscopy and X-ray crystallography. (C) 1999 Elsevier Science S.A. All rights reserved.
