Recent advances in the sulfonylation of C-H bonds with insertion sulfur dioxide are summarized. Usually, a surrogate, DABCO·(SO2)2, is used, which avoids utilization gaseous transformation. Inorganic sulfites such as sodium metabisulfite also effective C(sp3)-H bond sulfonylation. under transition metal catalysis or through radical process has been developed. In some cases, can be performed catalyst- and additive-free conditions, facilitated by visible light irradiation. The efficiency investigated merging catalysis.

Abstract Various practical methods for the selective C−H functionalization of ortho and recently also meta position an arene have already been developed. Following our recent development directing‐group‐assisted para toluene derivatives, we herein report first remote phenol derivatives by using a recyclable silicon‐containing biphenyl‐based template. The effectiveness this strategy was illustrated with different synthetic elaborations synthesis various phenol‐based natural products.

Sulfoxonium ylides act as an efficient carbene precursor in rhodium(III)-catalyzed C-H acylmethlyation of a variety arenes assisted by different chelating groups, and both aryl- alkyl-substituted β-carbonyl sulfoxonium are applicable. The system proceeded under redox-neutral conditions with broad scope, high efficiency, functional group tolerance.
