We present the first report of the use of dichlorobis(triphenylphosphine)palladium as a catalyst for the cyclization of suitably-substituted biphenyl ethers to dibenzofurans. This catalyst system affords higher yields and cleaner reactions than the more commonly used palladium acetate under phosphine-free conditions. The cyclization reaction utilizes an ortho-bromo diphenyl ether (I) to provide the dibenzofuran (II).
