The article presents a new methodology for ruthenium-catalyzed thiolation of alkanes and ethers using arylsulfonyl chlorides as a sulfur source.The Carbon–Hydrogen bond in a range of Alkanes and Ethers was effectively transformed into C–S bond to yield the corresponding sulfides in moderate to good yields.

A new, simple, and mild method for the synthesis of aryl alkyl sulfides from ethers and sodium sulfinate is developed. [ABSTRACT FROM AUTHOR]
