    • note
    • An ICP-AES analysis for palladium was conducted on the product mixture of 14bE after sequestration with PS-maleimide 3. ICP-AES analysis showed less than 1 ppm of Pd present with an expected theoretical value without sequestration of 91000 ppm. A second analysis on the same sample prior to sequestration had an actual value of 5 430 ppm. The difference between the theoretical and actual value was due to lack of solubility of the sample. Thus, >99.98% of palladium had been removed from the product mixture.
