The fluoroanisoles form a group of substances in chemistry that is derived from both anisole and fluorobenzene . The structure consists of a benzene ring with an attached methoxy group (–OCH 3 ) and fluorine (–F) as substituents . Their different arrangements ( ortho , meta or para ) result in three constitutional isomers with the empirical formula C 7 H 7 FO.
presentation
Fluoroanisoles can be prepared from the fluorophenols by etherification with dimethyl sulfate .
properties
The introduction of the fluorine atom changes the melting and boiling points only slightly compared to anisole (−37 ° C and 154 ° C).
