Abstract

Gaseous light hydrocarbons (LHs) are traditionally used as fuels, while their functionalization leads to wide applications of high economical values. Presented herein is the direct sulfonation of gaseous LHs by using SO₂ and O₂ gases. The in situ-generated trifluoroperacetic acid (TFAOOH) and bis(trifluoroacetyl) peroxide ((TFAO)₂) furnished the radical propagators trifluoroacetoxyl radicals (TFAO•) and HO•. The resultant trifluoroacetylsulfuric acid (TFAOSO₃H) efficiently sulfonated LHs under mild conditions and in good chemoselectivities.

期刊介绍： With an impact factor of 4.495 (2018), ChemCatChem is one of the premier journals in the field of catalysis. The journal provides primary research papers and critical secondary information on heterogeneous, homogeneous and bio- and nanocatalysis. The journal is well placed to strengthen cross-communication within between these communities. Its authors and readers come from academia, the chemical industry, and government laboratories across the world. It is published on behalf of Chemistry Europe, an association of 16 European chemical societies, and is supported by the German Catalysis Society.
