, (2017/11/27)
The invention discloses a selective hydrogenation reduction method of a fluorine-containing aromatic hydrocarbon derivative, and particularly discloses a preparation method of a compound shown in a general formula C1, C2 or C3. The preparation method comprises the following step of: reacting a compound shown in a general formula A1, A2 or A3 with a compound shown in a general formula B in the presence of a catalyst, thus forming the compound shown in the general formula C1, C2 or C3.

An effective and facile method for preparation of partially fluorinated aromatics via Nickel catalyzed, chelation-assisted ortho selective hydrodefluorination of polyfluoroarnes with triethylsilane has been developed, in which N-containing heterocycles were used as directing groups. The advantage of this protocol is its simple catalytic system with use of inexpensive and readily available NiCl2·6H2O as a catalyst.
