, (2020)
A new octahedron rhodium complex was synthesized, which permits the direct activation of terminal alkynes and its reaction with isatin derivatives under an air atmosphere. An excellent yield (up to 99%) was obtained at a catalyst loading of 2 mol%.

, p. 209 - 213 (2016/01/25)
N-Heterocyclic carbene (NHC) silver(I) complexes were employed efficiently in the alkynylation of ketones. These cationic complexes were highly active and efficient under mild conditions and in air without the need for an additive. The mechanism of this transformation was investigated. Experiments suggest that the formation of a silver acetylide key intermediate and the release of one ligand from the silver centre enable the transformation.
"On water"-promoted direct alkynylation of isatins catalyzed by NHC-silver complexes for the efficient synthesis of 3-hydroxy-3-ethynylindolin- 2-ones

supporting information; experimental part, p. 549 - 553 (2011/05/03)
The direct alkynylation of isatins catalyzed by NHC-Ag complexes via the activation of alkyne C-H bond on water was developed for the efficient synthesis of 3-hydroxy-3-ethynylindolin-2-ones under an air atmosphere. A remarkable rate-enhancement by water
