摘要：

1,2-Di(hatophenyl)ethenyl phenyl sulfones were prepared readily by successive treatment of halophenylmethyl sulfones with LiHMDS (lithium hexamethyldisilazide), halobenzaldehydes, diethyl chlorophosphate and LiHMDS. The di(halophenyl)ethenyl sulfones thus obtained were transformed successfully to aryleneethynylenes by Sonogashira coupling with arylethyne followed by LiHMDS-promoted elimination of phenylsulfinic acid.
