An efficient, recoverable fluorous organocatalyst for accelerating the DABCO-promoted Morita–Baylis–Hillman reaction

A convenient method for Morita–Baylis–Hillman reaction of arylaldehydes with methyl acrylate has been developed by using fluorous-tag organocatalyst 1-[4-(perfluorooctyl)phenyl]-3-phenylthiourea and DABCO at room temperature. The fluorous organocatalyst could be recovered from the reaction mixture by fluorous solid-phase extraction (F-SPE) with excellent purity for direct reuse.
