The article was titled 《Visible-light-promoted divergent functionalizations of methylenecyclopropanes》.COA of Formula: C4H3ClO2S2 The article contains the following contents:
Simple and convenient visible-light-promoted radical monofunctionalization and difunctionalization of methylenecyclopropanes via ring-opening and cyclization processes was developed for the syntheses of difluoromethyl compounds, alkyl compounds, halides, and sulfonyl compounds e.g., I in moderate to excellent yields. The methodologies feature a wide substrate scope and tolerate various functional groups. A possible radical mechanism was investigated and proven as a single electron transfer (SET) procedure.Thiophene-2-sulfonyl chloride(cas: 16629-19-9COA of Formula: C4H3ClO2S2) was used in this study.
Thiophene-2-sulfonyl chloride(cas: 16629-19-9) is a member of sulfonyl chlorides. Sulfonyl chlorides are reactive sulfonic acid derivatives similar in properties and reactivity to acid chlorides of carboxylates. The sulfonic acid group, however, is a highly hindered molecule, containing a tetrahedral configuration of substituents. COA of Formula: C4H3ClO2S2
