Yamamoto, Yoshihiko published the artcileSynthesis of ¦Ã-trifluoromethyl tetronate derivatives from squarates, Quality Control of 1206-46-8, the publication is Heterocycles (2017), 95(1), 525-539, database is CAplus.
Squarates and semisquarates were treated with TMSCF3 in the presence of a catalytic amount of AcONa in DMF at room temperature to afford 4-trifluoromethyl-4-hydroxycyclobutenones. Subsequent oxidative ring expansion of these products was performed using Pb(OAc)4 in the presence of MS 4A in 1,2-dichloroethane at 50¡ã to afford ¦Ã-trifluoromethyl tetronate derivatives
Heterocycles published new progress about 1206-46-8. 1206-46-8 belongs to catalysis-chemistry, auxiliary class Organic Silicones, name is Trimethyl(perfluorophenyl)silane, and the molecular formula is C6H20Cl2N4, Quality Control of 1206-46-8.
