Research Progress on the Synthesis Process of o-,m-,and p-difluorobenzene
This article systematically summarized the applications of o,m,and p-difluorobenzene in the fields of medicine,pesticide,energy,and electronics,and elucidated the important significance of the synthesis of o,m,and p-difluorobenzene.Next,four preparation process routes for synthesizing ortho,meta,and para difluorobenzene were summarized,and the best process route was obtained by comparing the four process routes.Finally,the synthesis process and development direction of aromatic fluorides were prospected.
