The reaction of trans-PtCl(COR)(PPh3)2 (1) (R=a, C6H5; b, C6H4-p-NO2; c, C6H4-p-CH3; d, C6H4-p-OCH3; e, CH3; f, Et; g, Prn; h, Hexn; i, CH2CH2Ph; j, But) with SnCl2 and SnCl2 plus H2 are described.The reactions with SnCl2 alone afford a mixture of trans-Pt(SnCl3)(COR)(PPh3)2 (2), and trans-PtCl(PPh3)2 (3) with 3 having a tin-oxygen bond.For 1f, 1h and 1j, reactions with SnCl2 plus H2 give aldehydes and platinum(II) hydride complexes, whereas for 1b and 1d, no aldehydes are obtained.The significance of these results in relation to H2 activation in the hydroformylation reaction is discussed. 31 P, 119 Sn, 195 Pt and, in a few cases, 13 C NMR data are presented.
