| Shrnutí: | Title screen ortho-Hydroxy-substituted aryliodonium salts were prepared by a two-step one-pot synthesis based on the reaction of 2-alkoxy-1-[(diacetoxy)iodo]arenes with arylboronic acids involving the initial formation of 2-alkoxyphenyl(aryl)iodonium salts and followed by deprotection of the intermediate product by boron tribromide. This procedure works well with halogen-, cyano-, 2-hydroxy-, 3-hydroxy-, 4-hydroxy-, methyl-, or trifluoromethyl-substituted arylboronic acids. Structures of three 2-hydroxyphenyl(aryl)iodonium bromides were confirmed by single crystal X-ray crystallography. The prepared 2-hydroxyphenyl(aryl)iodonium salts can be further converted to ortho-iodo-substituted diaryl ethers by treatment with a base via intermediate formation of the unstable aryliodonium betaines Текстовый файл |
