Three arylethynyl(phenyl)iodonium salts reacted as 1,3-dipolarophiles with two nitrile oxides to afford phenyl(substituted isoxazolyl)iodonium salts; these gave iodoisoxazoles on reaction with nucleophiles.Phenyl(phenylethynyl)iodonium toluene-p-sulphonate reacted in the same way with nitrones but the resulting phenyl(substituted isoxazolinyl)iodonium salts, with one exeption, were difficult to isolate because of ready hydrolysis.The crystal structure of 3-mesityl-5-phenylisoxazol-4-yl(phenyl)iodonium toluene-p-sulphonate has been determined.
