CoCl2 catalyzed trifluoroacetylation versus dimerization of methoxyaromatics using trifluoroacetic anhydride

Article abstract of DOI:10.1016/0040-4039(96)00870-2

Anisole, resorcinol dimethyl ether, p methylanisole, and β- methoxynaphthalene undergo regiospecific trifluoroacetylation in neat influoroacetic anhydride (TFAA) at 100 °C in the presence of 0.1 eq. CoCl₂ as catalyst, with a 1:1 anisole/TFAA ra
