Abstract: The most probable intermediate formed by interaction of CO and C2H4 with [(PPh3)3PtH]+ (I), in the synthesis of diethyl ketone from C2H4, CO and H2 under action of the catalytic system (PPh3)2Pt(OAc)2/PPh3/CF3COOH has been studied by 1H, 13C, 31P NMR spectroscopy. Complex I readily reacts with CO in CF3COOH solutions to form a carbonyl hydride complex trans-[(PPh3)2Pt(CO)H]+ (II). In contrast to I, II undergoes ethylene insertion at the PtH bond in the presence of a catalytic additive Sn(OAc)2. The carbonyl ethyl complex trans[(PPh3)2Pt(CO)C2-H5)]+ (III) formed quantitatively from this insertion is stable to isomerization to the corresponding complex indicating that the carbonylation of the Pt-ethyl bond is the rate-determining step of the diethyl ketone synthesis.
