Kawachi, Atsushi published the artcileo-(Fluorodimethylsilyl)phenyllithium as a Versatile Reagent for Preparation of Unsymmetrical, Silicon-Functionalized o-Disilylbenzenes, Quality Control of 312-40-3, the publication is Organometallics (2007), 26(19), 4697-4699, database is CAplus.
O-(Fluorodimethylsilyl)phenyllithium (1) was prepared by Br-Li exchange between o-C6H4(SiMe2F)Br (2) and t-BuLi in Et2O at -78¡ã. The electrophilic Si-F functionality in 1 is not attacked by the nucleophilic aryllithium moiety at that temperature 7Li, 19F, and 29Si NMR analyses supported by DFT calculations suggested that the structure of 1 involves an intramol. coordination of the F substituent to the Li atom. Reactions of 1 with halosilanes produced unsym., Si-halogenated o-disilylbenzenes 4.
Organometallics published new progress about 312-40-3. 312-40-3 belongs to catalysis-chemistry, auxiliary class Organic Silicones, name is Difluorodiphenylsilane, and the molecular formula is C12H10F2Si, Quality Control of 312-40-3.
