Abstract
The compound [Ru2(CO)4(µ3-MeCO2-O,O′)2(PBun 3)2] under hydrogen (170 atm), between 140 and 200 °C, undergoes rearrangements. Several phosphine-and phosphide-substituted ruthenium carbonyl hydrides are formed. Among them, [Ru3(µ-H)2(CO)7(µ3-PBun)(PBun 3)2], [Ru6(µ-H)6(µCO)(CO)12(µ-PBun 2)(PBun 3)2(µ6-P)], and [Ru7(µ-H)8(CO)12(µ3-PBun)(µ-PBun 2)-PBun 3)3(µ6-P)] were isolated and identified. The X-ray crystal structure analyses performed on the three new products have shown boat metal clusters for the last two, containing an encapsulated phosphide ligand.Keywords
