Transition metal-catalyzed carbon-carbon bond activation.
This tutorial review deals with recent developments in the activation of C-C bonds in organic molecules that have been catalyzed by transition metal complexes. Many chemists have devised a variety of strategies for C-C bond activation and significant progress has been made in this field over the past few decades. However, there remain only a few examples of the catalytic activation of C-C bonds...
متن کاملAn efficient and general route to reduced polypropionates via Zr-catalyzed asymmetric CC bond formation.
An efficient and general method for the synthesis of reduced polypropionates has been developed through the application of asymmetric carboalumination of alkenes catalyzed by dichlorobis(1-neomenthylindenyl)zirconium [(NMI)(2)ZrCl(2)]. In this investigation, attention has been focused on those reduced polypropionates that are alpha-monoheterofunctional and either omega-ethyl or omega-n-propyl. ...
متن کاملCobalt-catalyzed C-SMe bond activation of heteroaromatic thioethers.
Cobalt-catalyzed activation of methylthio-substituted N-heterocycles facilitates either cross-coupling reactions with aryl- or benzylzinc compounds or synthesis of the corresponding zinc compounds.
متن کاملNickel-Catalyzed Intramolecular C-O Bond Formation: Synthesis of Cyclic Enol Ethers.
An efficient and exceptionally mild intramolecular nickel-catalyzed carbon-oxygen bond-forming reaction between vinyl halides and primary, secondary, and tertiary alcohols has been achieved. Zinc powder was found to be an essential additive for obtaining high catalyst turnover and yields. This operationally simple method allows direct access to cyclic vinyl ethers in high yields in a single step.
متن کاملLigand-free nickel-catalyzed C-S bond formation: synthesis of 2-aminobenzothiazoles
A Ni-catalyzed C-S bond forming reaction has been developed for the synthesis of 2-aminobenzothiazole by the coupling of 2-haloanilines (-bromo and -iodo) with isothiocyanates. The key advantages of this procedure are ligand-free condition, inexpensive catalyst, high yields, and simple purification of the products by nonchromatographic technique.
