Transition metal catalyzed manipulation of non-polar carbon–hydrogen bonds for synthetic purpose
The direct addition of ortho C-H bonds in various aromatic compounds such as ketones, esters, imines, imidates, nitriles, and aldehydes to olefins and acetylenes can be achieved with the aid of transition metal catalysts. The ruthenium catalyzed reaction is usually highly efficient and useful as a general synthetic method. The coordination to the metal center by a heteroatom in a directing grou...
متن کاملRearrangement of alkynyl sulfoxides catalyzed by gold(I) complexes.
Recently, gold-carbenoid species have been proposed as intermediates in gold-catalyzed enyne rearrangements.1 Additionally, the reaction of gold complexes with propargyl esters has been developed as an alternative approach to metal carbenoids capable of effecting olefin cyclopropanation;2,3 however, to date, the reaction of electrophilic metals with alkynes has not been amenable to the generati...
متن کاملSynthesis of transition metal isocyanide compounds from carbonyl complexes via reaction with Li[Me3SiNR].
The reaction between a transition metal carbonyl compound, L(n)MCO, and Li[Me(3)SiNR] yields the corresponding isocyanide derivative, L(n)MCNR, thereby providing a new route to transition metal isocyanide compounds that does not require the use of free isocyanides as reagents.
متن کاملGold(I)-catalyzed 5-endo-dig carbocyclization of acetylenic dicarbonyl compounds.
The importance of cyclopentanoid natural products continues to inspire the development of methods for the synthesis of 5-membered rings. For example, the Conia–ene reaction provides an atomeconomical synthesis of methylenecyclopentanes by the thermal cyclization of e-acetylenic carbonyl compounds. While the classic thermal reaction is limited to the exocyclic cyclization mode, group 6 metal com...
متن کاملHighly efficient [2,3]-sigmatropic rearrangement of sulfur ylide derived from Rh(II) carbene and sulfides in water
Introduction Since their discovery in the late 1960s, the [2,3]-sigmatropic rearrangements of sulfonium ylides have received considerable attention because of their applications in organic synthesis and their probable involvement in biochemical processes. The most common method for sulfonium ylide generation involves the removal of a proton from a sulfonium salt with a strong base. However, a m...
