Abstract
In this paper we report the reaction of [Ru(η5-C5H5)Cl(PPh3)2] with P{CH2N(CH2CH2)2O}3 in the presence of NaBF4, in which, apart from the Cl? substitution, an unexpected P–C bond cleavage in the tertiary phosphane is observed. It results in the formation of [Ru(η5-C5H5)(PH{CH2N(CH2CH2)2O}2)(PPh3)2]BF4 (1) – the first “piano-stool” ruthenium complex with a secondary aminomethylphosphane ligand.
