This is the first example in which a recyclable, heterogeneous copper fluorapatite catalyst is used for the arylation of phenols with arylboronic acids at room temperature in the presence of Cs2CO3 as a base and methanol as a solvent. The catalyst was recovered and reused several times without loss of catalytic activity.</p>1 aMulla, Shafeek, Abdul Rash1 aInamdar, Suleman, M.1 aPathan, Mohsinkhan, Y.1 aChavan, Santosh, S.  uhttps://library.ncl.res.in/content/base-promoted-highly-efficient-copper-fluorapatite-catalyzed-coupling-phenols-arylboronic-0
