Verhoog, Stefan published the artcileSilver-Mediated 18F-Labeling of Aryl-CF3 and Aryl-CHF2 with 18F-Fluoride, Formula: C11H8F2, the publication is Synlett (2016), 27(1), 25-28, database is CAplus.
We report the synthesis of [18F]arylCF3 and [18F]arylCHF2 derivatives from arylCF2Br and arylCHFCl precursors applying a silver-mediated halogen exchange with [18F]fluoride. In the absence of Ag(I)OTf, no reaction takes place at room temperature for both classes of substrates; this result demonstrates the beneficial role of silver(I) as a means to induce 18F-incorporation under very mild conditions.
Synlett published new progress about 53731-26-3. 53731-26-3 belongs to naphthyridine, auxiliary class Difluoromethyl,Fluoride,Naphthalene, name is 1-(Difluoromethyl)naphthalene, and the molecular formula is C9H9BrO2, Formula: C11H8F2.
