Diphenyliodonium-2-carboxylate, as reagent for generation of benzyne

DiphenyI-3-ethylpentane, 48, 82 Diphenyliodonium-2-carboxylate, as reagent for generation of benzyne,... 

Diphenyliodonium-2-carboxylate monohydrate. Mol, wt, 341,13, m.p, 220°, dec. This stable and safe reagent is useful for the generation of benzyne in an aprotic solvent in the presence of a reactive diene as trapping agent. The original preparative procedure has been improved to a point such that 2 g. of o-iodobenzoic acid (Aldrich, Eastman) can be converted into 2.1 g. of the benzyne precursor in li-2 hrs. working time. The synthesis of 1,2,3,4-tetraphenylnaphthalene can be...
