A new method for the preparation of perfluoroalkylated triphenylethylene derivatives
Jeong, In Howa,Won, Deok Hee,Jeon, Sung Lan
, p. 5905 - 5908 (1996)
The reaction of perfluoroalkylated dithioketals 1 with 2.1 equiv. of phenyllithium afforded the corresponding vinyl sulfides 2 in good yields. Treatment of vinyl sulfones 3, obtained from the oxidation of 2, with phenyllithium derivatives resulted in the
