Abstract
The cluster HRu3(CO)(9)[NS(O)MePh] (1) reacts with two equivalents of MeC=C Me in tetrahydrofuran at 60 degrees C to give the dienonyl derivative Ru-3( CO)(7)[NS(O)MePh] (HCMeCMeCMeCMeCO) (2), along with an isomer mixture of Ru -3(CO)(8)[NS(O)MePh] (HCMeCMe) (3). At 100 degrees C, the same reaction giv es rise to the formation of the diendiyl cluster Ru-3(CO)(8)(CMeCMeCMeCMe) (4). The single-crystal structure analyses reveal for 2 a closed Ru-3 skele ton and for 4 an open Ru, framework. (C) 1999 Elsevier Science S.A. All rig hts reserved.
