A wide range of organosulfur compounds are known which contain one or more halogen atom ("X" in the chemical formulas that follow) bonded to a single sulfur atom, e.g.: sulfenyl halides, RSX; sulfinyl halides, RS(O)X; sulfonyl halides, RSOX; alkyl and arylsulfur trichlorides, RSCl and trifluorides, RSF; and alkyl and arylsulfur pentafluorides, RSF. Less well known are dialkylsulfur tetrahalides, mainly represented by the tetrafluorides, e.g., RSF.
