Copper and l -sodium ascorbate catalyzed hydroxylation and aryloxylation of aryl halides
摘要:
CuSO4 center dot 5H(2)O and NaAsc catalyzed hydroxylation and C-O/C-S cross-coupling reactions of aryl halides with phenols or 4-methylbenzenethiol were described. A wide range of substrates and test cases highlight the synthetic utility of the approach. A series of phenols, diaryl ethers, allcylaryl ethers, and diaryl thioethers were synthesized in high yield.

The synthesis of aryl ethers from phenols and alcohols using polymer-bound triphenylphosphine and diethyl azodicar☐ylate (DEAD) is described. The polymer-bound triphenylphosphines are easily removed by filtration from the reaction products. This method is operationally simple and provides the products with high purity and in good yields.
