Arsenic pentafluoride (AsF5) adds across the CC and CS double bonds of H2C = SF4, F3C-CH = SF4 and F2C = CH-SF, with the formation of AsF4-CHR-SF5 (R = H, CF3). In the case R = CF3, a stable compound is obtained. Crystallography reveals a structure with a trigonal bipyramidally coordinated arsenic and the carbon substituent in an equatorial position. For R = H, the primary product dimerizes to (F5S-CH2)2AsF2+ AsF6-. Its first hydrolysis product (F5S-CH2)2AsFO.AsF5 was identified via its crystal structure.
