The kinetics of the reaction of bipyridyl with potassium trichloro (2,5-dimethyl 3-hexyne 2,5-diol)platinate(II)

摘要: Abstract The substitution reaction of bipyridyl with potassium trichloro (2,5-dimethyl 3-hexyne 2,5-diol) platinate(II) has been studied in 90% methanol -10 water mixtures at various temperatures. proceeds several steps which two have well defined. Two rate constants were measured 25°C: k 1obs = 25 × 10 −3 sec −1 2obs 0.2 first constant depends on the concentration and second is independant concentration. found compared those Zeise's salt suggest a greater trans effect for acetylenic glycol, as to ethylene
