Diaryliodonium fluoroalkyl sulfonate salts and a method of making

A cyclic diaryliodonium sulfonate salt having the formula:

• ##STR5## wherein m represents an integer of 0 or 1, when m is zero, the carbons at the aryl positions ortho to the iodine being directly linked by a single carbon-carbon bond;
• L is an electron neutral or electron donating group selected from the group consisting of --O--;
• --NR.sup.12 --, wherein R.sup.12 represents --H or an alkyl group;
• and --(CR.sup.13 R.sup.14)n-- wherein R.sup.13 and R.sup.14 each independently represent --H or an alkyl group and n represents an integer of 1 to 2;
• R1, R2, R3, R4, R7, R8, R9, and R10 are each independently selected from the group consisting of electron neutral groups and electron withdrawing groups, wherein adjacent R1, R2, R3, R4, R7, R8, R9, R10 groups optionally may together form a ring;
• and
• R11 is selected from the group consisting of halide groups, alkyl groups, chlorofluoroalkyl groups, chlorinated alkyl groups, and fluorinated alkyl groups.
