Reactivity of the Ru-O bond in η2(O,P) -chelated mono(ether-phospine) (pentamethylcyclopentadienyl) ruthenium(II) complexes

By treatment of the 16-electron starting compound Cp * RuCl(P ～ O) (1) (Cp * = η5-C5Me5; P ～ O, 1(P)-coordinated ether-phosphine ligand Cy2PCH2CH2OCH3) with L = CO (a) and P(OEt)3 (b), the carbonyl and mixed bisphosphine ruthenium(II) complexes Cp * RuCl(L)(P ～ O) (2a, 2b) are accessible. Chloride abstraction from 2a, 2b with NaBPh4 leads to the chelated complexes [Cp * Ru(L)(P ∩ O)][BPh4] (3a, 3b) (P ∩ O, η2(O,P)-coordinated ligand). Cleavage of the Ru-O bond in 3a, 3b with sulphur dioxide results in the formation of the η1-SO2 complexes [Cp * Ru(L)(P ～ O)(η1-SO2)][BPh4] (4a, 4b) in which the O2SRu fragment adopts a trigonal planar geometry. In a similar way the Ru-O bond is easily ruptured when [Cp * Ru(CO)(P ∩ O)][BPh4] (3a) is reacted with ethene and phenylacetylene to give the adduct [Cp * Ru(CO)(P ～ O)(η2-C2H4)][BPh4] (5a) and the η1 -vinylidene complex [Cp * Ru(CO)(P ～ O)(=C=CHPh)][BPh4] (6a) respectively.
