| Abstract: | Platinum(II) hydridotin complexes containing bulky phosphine ligands, trans-Pt(H)L2(SnR3) have been prepared from: (i) the equimolar reaction between corresponding platinum(II) dihydride complexes and HSnR3 (Cy = cyclohexyl), P-i-Pr3, P-t-BuPh2, P-t-Bu2Me; R = Ph), (ii) the oxidative addition of the corresponding zerovalent complexes, Pt0L2, with HSnR3 (L = P-i-Pr3, P-t-BuPh2; R = Ph), (iii) the reaction of the corresponding platinum(II) dihydride complexes with ClSnR3 in the presence of pyridine in benzene (L = P-i-Pr3, P-t-BuPh2; R = CH3, n-Bu), (iv) the sodium borohydride reduction of the corresponding hydridochloride complexes Pt(H)Cl(PR3)2 with ClSnR3 in THF (L = PCy3; R = Ph), these compounds have been characterized by their elemental analysis, infrared, 1H and 31P NMR spectral data. |
