, p. 9618 - 9626 (2021)
Compounds of main-group elements such as silicon are attractive candidates for green and inexpensive catalysts. For them to compete with state-of-the-art transition-metal complexes, new reactivity modes must be unlocked and controlled, which can be achiev

The highly efficient and selective C(sp3)–S bond cross-coupling method for the synthesis of 9-thiolated fluorenes through a direct thiolation at 9-C(sp3)–H of fluorenes with thiols is described. This reaction occurs at ambient conditions and shows good tolerance of functional groups including arylthiols and alkylthiols. A wide range of products is obtained in moderate to good yields. Besides, the reaction of benzothiophenol and fluorine generates unexpected 9-benzylidene-9H-fluorene by eliminating hydrogen sulfide.
