Title: Spectroscopic and structural characterization of 2,4,6-tris(trifluoromethyl)phenyllithium·Et<sub>2</sub>O: a dimer stabilized by lithium ⋯ fluorine contacts
Abstract:1,3,5-Tris(trifluoromethyl)benzene reacts with butyl-lithium in ether/hexane to form 2,4,6-tris(trifluoromethyl)phenyl-lithium which has been characterized by low-temperature single-crystal X-ray anal...1,3,5-Tris(trifluoromethyl)benzene reacts with butyl-lithium in ether/hexane to form 2,4,6-tris(trifluoromethyl)phenyl-lithium which has been characterized by low-temperature single-crystal X-ray analysis and NMR methods; the molecule exists as a dimer in which each lithium is stabilized by bonding to two carbon atoms, an oxygen of a diethyl ether molecule, and two fluorines from ortho-CF3 groups.Read More
