摘要：

Treatment of [(eta(5)-C5R5)Ru(L)(2)]BF4 (R = Me, (L)(2) = dppe; R = H, (L)(2) = (PPh3)(2)) with 0.45 equiv of HC=CCH(OH)C=CH led to the formation of the C5H2-bridged compounds [(eta(5)C(5)R(5))(L)(2)Ru=C=C=CHCH=C=Ru(L)(2)(eta(5)-C5R5)](BF4)(2). The C5H2-bridged compounds reacted with alumina to give the C5H-bridged compounds [(eta(5)-C5R5)(L)(2)Ru=C=C=CHC=CRu(L)(2)(eta(5)-C5R5)]BF4. The structure of the C5H-bridged complex [Cp(PPh3)(2)Ru=C=C=CHC=CRu(PPh3)(2)Cp]BPh4 has been confirmed by X-ray diffraction and shows the bridging C5H ligand to be symmetric with a delocalized st-system. Reaction of [(eta(5)-C5R5)(L)(2)Ru=C=C=CHC=CRu(L)(2)(eta(5)-C5R5)]BF4 with acetone in the presence of KOH or KOBut produced (eta(5)-C5R5)(L)(2)RuC=CCH(CH2COMe)C=CRu(L)(2)(eta(5)-C5R5).
