الإجراء التجريبي

The aromatic iodonium complex salts may be prepared by metathesis of corresponding aromatic iodonium simple salts (such as, for example, the diphenyliodonium bisulfate) in accordance with the teachings of Beringer, et al., J. Am. Chem. Soc. 81, 342 (1959). Thus, for examples, the complex salt diphenyliodonium tetrafluoroborate is prepared gy the addition at 60° C. of an aqueous solution containing 29.2 g. (150 millimoles) silver fluoroborate, 2 g. fluoroboric acid, and 0.5 g. phosphorous acid in about 30 ml. of water to a solution of 44 g. (139 millimoles) of diphenyliodonium chloride. The silver halide that precipitates is filtered off and the filtrate concentrated to yield diphenyliodonium fluoroborate which may be purified by recrystallization.
