Descripción general

Sulfoxonium ylides are highly stable carbene precursors, serving as a safer alternative to diazo compounds as they that do not generate gases as byproducts. Sulfoxonium ylides have been shown to be effective in a wide array of transition metal catalyzed C-H functionalization and coupling reactions.

A general, mild, and versatile synthesis of the challenging α-aryl-β-ketosulfoxonium ylides has been developed for the first time, substituting traditional methods starting from diazo compounds. The arylation of easily accessible β-ketosulfoxonium ylides using aryne chemistry allowed the preparation of a

A Cp*Co(III)-catalyzed C-H bond functionalization of a range of arenes by employing sulfoxonium ylides as carbene precursors instead of diazo compounds and other carbene precursors has been established. This reaction is highly efficient without any additive, possesses high step and

Rh(III)-catalyzed cascade C-H activation of benzoylacetonitriles and annulation with sulfoxonium ylides was realized, leading to selective synthesis of naphthols, 2,3-dihydronaphtho[1,8- bc]pyrans, and naphtho[1,8- bc]pyrans. This step-economic reaction proceeded efficiently under mild and redox-neutral conditions via multiple C-H activations.

Direct and efficient synthesis of 1-naphthols has been realized via Rh(III)-catalyzed C-H activation of sulfoxonium ylides and subsequent annulation with alkynes, where the sulfoxonium ylide functioned as a new traceless bifunctional directing group. This reaction occurred under redox-neutral conditions with
