Abstract
A sulfoxide compound and method of producing benzothiophene derivatives using the same are provided. The sulfoxide compound is represented by formula (I), wherein R1 and R2 are individually and independently benzoyl group; alkyl, acyl or silyl group of C1-C6 straight chain or branched chain; or alkenyl group of C3-C6 straight chain or branched chain; and X is halogen atom. The sulfoxide compound reacts with alkynyl compound, and then the synthesis efficiency of benzothiophene derivatives can be effectively increased.
