Copper and l-Sodium ascorbate (cas 134-03-2) catalyzed hydroxylation and aryloxylation of aryl halides

Add time:09/30/2019    Source:infona.pl

CuSO4·5H2O 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, alkylaryl ethers, and diaryl thioethers were synthesized in high yield.
