| Abstract: | The formation of the compound RSnX(acac)2 (acac = 2,4-pentanedionato) by reaction of bis(2,4-pentanedionato)tin(II) on a halide RX with R = CH3, C2H5, C4H9, C6H5, CH2I, (C6H5)3SnCH2, (C2H5)3SnCH2 and X = I, Br has been studied by polarography. At 25°C, it is in fact an equilibrium whose constant has been measured. The intermediate formation of the ion-pair RSn(acac)2+X?] has allowed us to explain the experimental results. |
