摘要：

XeF2 reacted at room temperature in dichloromethane in the presence of HF with triphenylethene, 9-benzylidenefluorene and tetraphenylethene to form vicinal difluorides in high yield, the relative reactivities being in the following order: 1,1-diphenylethene:triphenylethene:tetraphenylethene:9-benzylidenefluorene = 0.4:1:1.1:0.2. CsSO4F did not react at 35-degrees-C with phenyl substituted alkenes in dichloromethane, while vicinal fluoro-methoxy adducts were formed in the presence of methanol. The methoxy group entered according to the Markovnikov rule for regioselectivity in the case of triphenylethene and 9-benzylidenefluorene, with the relative reactivities: 1,1-diphenylethene:tri-phenylethene:tetraphenylethene:9-benzylidenefluorene = 1.2:1:0.2:0.3.
