| Abstract: | Acid-catalysed bridge cleavage reaction ofthe compound [(BigHb Co-µ-(OH)2 - Co(BigH)24+ has been investigated spectrophotometrically with both perchloric and nitric acids in the temperature range 42°-60°. In acid medium, rupture of first bridge is rate determining while breakage of the second bridge is fast. Bridge cleavage reaction proceeds only through the acid-catalysed path. Rate equations, rate constants and activation parameters (ΔH‡ ,44.3±3.3 kJ mol-1, ΔS‡ -188±18 JK-1 mol-1) are similar in both the perchloric and the nitric acids. |
