Aryl boronic acids or pinacol esters containing EDG were converted in good yields and fast reactions to the corresponding aryl fluorides using the readily obtainable solutions of AcOF. In reactions with aryl boronic acids containing EWG at the para position, there are two competing forces: one directing the fluorination to take place ortho to the boronic acid and the other, toward an ipso substitution. With EWG meta to the boronic acid, substitution ipso to the boron moiety takes place in good yields.
A process for the preparation of o-chlorofluorobenzene
-
, (2008/06/13)
ο-Chlorofluorobenzene is prepared from 1,2,3-trichlorobenzene by partial fluorine exchange to a mixture of 2,6-dichlorofluorobenzene and 2,3-dichlorofluorobenzene followed by selective reduction to a mixture of fluorobenzene, ο-chlorofluorobenzene and 2,3-dichlorofluorobenzene. Each of the components of this latter mixture can be separated by a relatively easy distillation, and each has value as an intermediate in the manufacture of other valuable organic chemicals.
