title: C(aryl)-O bond formation from aryl methanesulfonates via consecutive deprotection and S(N)Ar reactions with aryl halides in an ionic liquid.
abstract: An efficient K3PO4-mediated synthesis of unsymmetrical diaryl ethers using the ionic liquid [Bmim]BF4 (1-butyl-3-methylimidazolium tetrafluoroborate) as solvent has been developed. The procedure involves consecutive deprotection of aryl methane-sulfonates and a nucleophilic aromatic substitution (S(N)Ar) with activated aryl halides.
