Abstract
Abstract The kinetics of the reactions [Pt(N-N)(SCN)2]+*-tn→[Pt(N-N)(SCN)(tu)]++SCN− have been investigated for N-N=ethylenediamine (en), N,N′-dimethylethylenediamine (N,N′-Me2-en), N,N′-diethylenediamine (N,N′-Et2-en) and N,N′-diisopropylethylenediamine (N,N′-iPr2-en) in DMF. A second reaction [Pt(N-N)(SCN)(tu)]++tu→[Pt(N-N)(tu)2]2++SCN- occurs, the kinetics of which were determined for N-N=en and N,N′-iPr2-en. Activation parameters are reported and discussed in terms of steric effects. Two effects of bulky groups on activation parameters are described and discussed. A novel linkage isomerization leading to an equilibrium mixture of thiocyanato and isothiocyanatoplatinum(II) complexes has been characterised.
