摘要
Attempts to generate a difluorovinyl sulfone and to react it with cyclopentadiene were hindered by the formation of hydrofluorination products. An alpha-carbamoyloxy-beta,beta-difluoroethenyl phenyl sulfone has been prepared in high yield, but reactions with cyclopentadiene have given predominantly mono-fluorinated cycloadducts, via reduction of the difluorinated compound in situ.
