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.
