Description
The catalytic effects of insoluble phosphonates bound to polystyrene and silica gel on the iodine exchange between short and medium chain primary alkyl iodides and anhydrous carrier-free Na131I under biphasic conditions have been investigated. Polymeric diethyl and diisopropyl benzylphosphonate exhibited significant catalytic efficiencies. The use of the polar silica gel support resulted in a lower catalytic activity compared to the polystyrene resin. (author)
