Preparative Methods add jo-toluenesulfonhydrazide in methanol dropwise to an equimolar amount of benzeneseleninic acid in methanol at 0°C cool at —5°C overnight, filter the highly pure crystalline selenosulfonate (96% yield) alternatively, use 2 equiv of / toluenesulfinic acid instead of p-toluenesulfonhy-drazide several other preparative methods are also available 5e-phenyl benzeneselenosulfonate can be prepared in the same way and can be used similarly for most purposes.
