Stoyanovich, F. M.; Marakatkina, M. A. published the artcile< Formation of 3-lithio-4,5-dehydrotoluene from 4-fluoro-3,5-dibromotoluene>, Synthetic Route of 112-63-0, the main research area is lithiodehydrotoluene; benzyne lithium derivative; dehydrotoluene lithio.
Treating 4,3,5-Br(F)2C6H2Me with BuLi at -90° gave only 2,3,5-F(Br)(Me)C6H2CO2H after carbonation, but analogous reaction at -70° gave 4,3,5-Bu(HO2C)2C6H2Me via the title benzyne (I). I also gave dimers II (R = H, CO2H), and reacted with LiNPh2 to give 4,3,5-Ph2N(R)2C6H2Me (same R).
Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya published new progress about Elimination reaction. 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Synthetic Route of 112-63-0.
