General Description

(Trifluoromethoxy)benzene is an aryl trifluoromethyl ether. (Trifluoromethoxy)benzene can be prepared from 4-chloro-1-(trifluoromethoxy)benzene via hydrogenolysis. Conformation of (trifluoromethoxy)benzene in the gas phase has been studied by electron diffraction and spectroscopy supplemented with ab initio calculations.
