M. Ino et al., PHOTO-CONTROL OF ANION RELEASE BY DIALKYL PHENACYLSULFONIUM SALT IN WATER 1,2-DICHLOROETHANE 2-PHASE SYSTEM/, Nippon kagaku kaishi, (8), 1993, pp. 982-984
Dialkylphenacylsulfonium salt undergose photoinduced transformation in
to an ylide form with concomitant release of anion. As this transforma
tion is reversible, we prepared oil-soluble dibutyl(4-methoxyphenacyl)
sulfonium percholorate (3), which in 1,2-dichloroethane showed an abil
ity to control perchlorate concentration of the aqueous phase in the o
rganic/aqueous tow-phase system by UV-irradiation. Photo-driven active
transport of perchlorate through an organic layer by 3 as a carrier w
as also examined.
