Carbonylation of Cyclotrisilenes

Angewandte Chemie - International Edition, 2013
Carbon monoxide (CO) is a common ligand in transitionmetal chemistry. In organic chemistry, it is frequently used to introduce a C1 unit, although carbonylations, such as hydroformylation or the Pauson–Khand reaction, generally require a transition-metal catalyst, even for strained (and thus highly reactive) cyclic compounds.

Nickel-Catalyzed Four-Component Carbonylation of Ethers and Olefins: Direct Access to γ-Oxy Esters and Amides.

Angewandte Chemie, 2022
Multi-component carbonylation of olefins, a reaction that installs both a carbon-carbon(heteroatom) bond and a carbonyl group across the double bond, is an attractive strategy for alkene functionalization.

A Visible Light Driven Nickel Carbonylation Catalyst: The Synthesis of Acid Chlorides from Alkyl Halides.

Angewandte Chemie, 2022
We describe here the development of a visible light driven nickel carbonylation catalyst. The combination of the large bite-angle Xantphos ligand with nickel(0) generates a catalyst capable of activating alkyl halides toward carbonylation at ambient ...

Enantioselective Double Carbonylation Enabled by High-Valent Palladium Catalysis.

Journal of the American Chemical Society, 2022
Palladium-catalyzed carbonylation reactions are efficient methods for synthesizing valuable molecules. However, realizing a carbonylation with excellent yield and chemo-, regio-, and enantioselectivities by classical low-valent palladium catalysis is ...

A dual light-driven palladium catalyst: Breaking the barriers in carbonylation reactions

Science, 2020
Lighting the way coming and going Catalysts accelerate chemical reactions by breaking existing bonds and then forming new ones. Often, the factors that favor the first process can muddle the second one, constraining a catalyst's generality. Torres et al.
