Key words

nickel catalysis - carbon nitride - cross-coupling - photoredox catalysis - aryl halides - alcohols

Significance

Nickel-coordinated graphitic carbon nitride (Ni/g-C3N4), prepared according to Equation 1, catalyzed the C–O cross coupling of aryl bromides with alcohols under visible-light irradiation to give the corresponding aryl ethers in ≤95% isolated yield.

Comment

The preparation of g-C3N4 has been previously reported (X. Li et al. J. Phys. Chem. ­Solids, 2014, 75, 441). In the C–O cross coupling of 4′-bromo­acetophenone with MeOH, Ni/C3N4 was recovered and reused four times without ­significant loss of its catalytic activity.
