The first ligand is bound to the metal in a P,N-bidentate coordination mode and with cis geometry, independently of the reaction temperature. Synthesis of a platinum complex with the second ligand at room temperature, afforded a mixture comprising 86% of a neutral cis complex, in which the ligand is bound to the metal only via the two P-donors, and 14% of a P,N,P-terdentate ionic complex where the two P atoms are trans to each other. On the other hand, synthesis of the complex at 100 °C, led almost exclusively to the formation of the cis-Pt complex in a P,P-bidentate coordination mode. The complexes were tested as catalysts without any promoting additive for the hydrogenation of trans-cinnamaldehyde under mild reaction conditions and displayed selectivity for the formation of cinnamyl alcohol of up to 67%. %> Αποθετήριο Ήλιος / ΕΙΕ
