Catalytic carbene-transfer reactions constitute a class of highly useful transformations in organic synthesis. Although catalysts based on a range of transition-metals have been reported, the readily accessible nickel(II)-based complexes have been rarely used. Herein, an air-stable nickel(II)-carborane complex is reported as a well-defined, versatile and recyclable catalyst for selective carbene transfer reactions with low catalyst loading under mild conditions. This catalyst is effective for several types of reactions including diastereoselective cyclopropanation, epoxidation, selective X?H insertions (X = C, N, O, S, Si), particularly for the unprotected substrates. This represents a rare example of carborane ligands in base metal catalysis.
Gold (I) catalysis of X-H bond insertions
Mangion, Ian K.,Weisel, Mark
experimental part, p. 5490 - 5492 (2010/10/20)
The utility of gold catalysis for carbene X-H bond insertion chemistry is described for the first time, taking advantage of the unique reactivity of sulfoxonium ylides as metal carbene precursors.
Stereoselective insertion of rhodium carbenoid to water under control with intramolecular participation of hydroxy group
Sugimura, Takashi,Nagai, Takao
, p. 286 - 287 (2008/09/20)
A chiral diazo ester having a hydroxy group in the proper geometry produces an adduct with water up to 92% de upon treatment with a rhodium catalyst. This high stereoselectivity is attributable to the intramolecular hydrogen bond between the internal hydroxy group and the rhodium carbenoid. Copyright
