Abstract

A method for preparing an aromatic sulfide or a salt thereof is provided. The method for preparing an aromatic sulfide or a salt thereof includes reacting a compound having a structure represented by Formula (I) to a compound having a structure represented by Formula (III) in the presence of a compound having a structure represented by Formula (II) to obtain a compound having a structure represented by Formula (IV) , wherein R 1 and R 2 are independently C 1-6 alkyl group, or C 5-7 cycloalkyl group; R 3 is independently C 1-6 alkyl group, C 5-7 cycloalkyl group, C 1-6 haloalkyl group, or aryl group; R 4 is independently H, or C 1-6 alkyl group; Y is H, aryl group, or -X-R 5 ; X is -O-, -NH-, -PH-,or -S-, or Y and an adjacent R 4 are optionally combined with the carbon atoms to which they are attached, to form an aryl group; and R 5 is H, C 1-6 alkyl group, C 5-7 cycloalkyl group, or aryl group; and Z - is R 3 SO 3 - .
