Abstract
The complex [Ru(C5H5)Cl(PPh3)2] reacted with 1 equivalent of dippe [dippe = 1,2-bis(diisopropylphosphino)ethane] in refluxing toluene to yield [Ru(C5H5)Cl(dippe)]1. The complex [Ru(C5Me5)Cl(dippe)]2 was obtained by reaction of [{Ru(C5Me5)(µ3-Cl)}4] with a stoichiometric amount of dippe in CH2Cl2. The crystal structure of 2 has been determined. Both 1 and 2 are non-electrolytes in non-polar solvents. In alcohols, compound 2 has a strong tendency to dissociate chloride. In the presence of air, this compound binds O2 irreversibly, yielding the dioxygen complex [RuC5Me5(O2)(dippe)]+, which is isolable as the [BPh4]– salt (3). The crystal structure of this compound has also been determined. Both 1 and 2 reacted with SnCl2 in CH2Cl2 to yield the insertion derivatives [Ru(C5R5)(SnCl3)(dippe)](R = H 4 or Me 5). All compounds were characterized by NMR spectroscopy and microanalysis.Keywords
