The present invention relates to a composition comprising one or a mixture of two or more quinoline-polyethylene glycol containing compound, each quinoline-polyethylene glycol containing compound comprising: one to three quinoline group and one or more polyethylene glycol group,
wherein, in each said quinoline-polyethylene glycol containing compound, one to three of said one to three quinoline group is connected via one or more oxygen atom of said one or more polyethylene glycol group via carbon 6 or carbon 8 of said one to three quinoline group.

Disclosed in the present invention were a fluorosulfonyl-containing compound, an intermediate thereof, a preparation method therefor and use thereof. The fluorosulfonyl-containing compound disclosed in the present invention comprises a cation and an anion, the cation being as shown in Formula (1). The fluorosulfonyl-containing compound of the present invention can react with a substrate to efficiently synthesize a fluorosulfonylation product, has low toxicity, was simple to prepare, was convenient to use, and was in a solid stable state at normal temperature. Furthermore, the compound has a wide range of adaptable substrates, including phenolic compounds and amine compounds, and was the only solid form agent that can achieve such a chemical conversion, and therefore has important academic and application value.
