Herein,　we　reported　the　straightforward　synthesis　of　thiomethylnaphthalenes　via　the　reaction　of　propargyl　alcohols　with　dimethyl　sulfoxide/thionyl　chloride　(DMSO/SOCl2),　which　also　provided　easy　access　to　deuterated　thiomethyl　and　other　thioalkyl　scaffolds　when　deuterated　dimethyl　sulfoxide　and　dialkyl　sulfoxides　were　used,　respectively.　In　addition,　the　thiomethyl　group　can　be　readily　derivatized　to　the　corresponding　sulfoxide,　sulfone,　and　sulfoximine　of　interesting　photophysical　properties.
