Autor: Ekkehard Lindner, Klaus Eichele, Riad Fawzi, Joachim Wald

Publikováno v: Journal of Organometallic Chemistry. 601:220-225

In refluxing toluene the tetradentate ligand (Ph2PCH2CH2OCH2)2 (1) reacts with Cl2Ru(PPh3)3 to give the stable η4-(O,O,P,P)-chelated ruthenium(II) complex trans-Cl2Ru(Ph2PCH2CH2OCH2)2 (2). With carbon monoxide no transformation to an η3-(O,P,
