2,2-Dihalo-2-(alkylthio)acetyl chloride, its manufacturing method, acetylation agent and compounds

Abstract

A compound represented by formula (1) or a acetic agent containing a compound represented by formula (1) is obtained by a manufacturing method comprising the following steps: acetic chlorination of a compound represented by formula (2) to obtain a compound represented by formula (3); and dihalogenation of a carbon atom at position 2 of the compound represented by formula (3). [In formula (1), R is an alkyl group, X' is a halogen group, and X" is a halogen group; in formulas (2) and (3), R is the same as R in formula (1).]
