摘要：
Disclosed is a method of preparing intermediates required for synthesis of natural carotenoid products using sulfone compounds, which is advantageous in terms of high preparation efficiency due to a relatively simple process. Specifically, there is provided the preparation method of 4-chloro-3-methyl-2-butenylphenylsulfide as a C5-unit compound for lengthening a carbon chain, and di(4-chloro-3-methyl-2-butenyl)sulfide as a C10-unit compound for forming a central polyene moiety. In addition, di(4-chloro-3-methyl-2-butenyl)sulfone as a selective oxide of the di(4-chloro-3-methyl-2-butenyl)sulfide and a preparation method thereof are provided.
