POLYFLUOROARYL ORGANOMETALLIC COMPOUNDS. XVII. 2,4,6-TRIS(TRIFLUOROMETHYL)PHENYLLITHIUM, A STERICALLY CROWDED SYSTEM
A lithium derivative (3) is generated from 1,3,5-tris(trifluoromethyl)benzene (2) and is shown to be remarkably stable.It is shown that 2 is less acidic than pentafluorobenzene, in competition for butyllithium.A preliminary survey of reactivity shows that
