Lopez-Serrano J, Duckett SB, Lledos A: Palladium-catalyzed hydrogenation: detection of palladium hydrides. J Am Chem Soc. 2006 Aug 2;128(30):9596-7.
A joint study using para-hydrogen-enhanced NMR spectroscopy and density functional theory.. Pd (PEt3) 2 (OTf) 2, acting as an in situ source of Pd (PEt3) 2, reacts with an alkyne and hydrogen via phosphine loss to form the detectable hydride-containing species Pd (PEt3) 2 (H)(CHPhCH2Ph), cis- and trans-Pd (PEt3) 2 (H)(CPh=CHPh), and Pd2 (PEt3) 3 (H)(CHPhCH2Ph) 2+, which map onto the reaction scheme predicted by density functional theory. |
