New catalytic strategies for DNA and RNA alkylation using rhodium (II) and copper (I) carbenes - a versatile tool for applications in chemical biology [PDF]
, 2015 A variety of nucleic acid substrates were catalytically alkylated with rhodium(II) and copper(I)-carbenoids generated from diazocarbonyl compounds. The alkylation took place via an N-H insertion reaction selectively targeting the nucleobases in single ...

Iridium-Catalyzed Asymmetric α-Allylic Alkylation of Amides using Vinyl Azide as Amide Enolate Surrogate [PDF]
, 2020 Among the unstabilized enolates used as nucleophile in iridium-catalyzed asymmetric allylic alkylation reactions, amide enolates are least explored. Vinyl azides are now employed as amide enolate surrogate for the first time in Ir-catalyzed asymmetric ...

Golden Opportunity: A Clickable Azide-Functionalized [Au25(SR)18]-Nanocluster Platform for Interfacial Surface Modifications [PDF]
, 2019 Ultrasmall atomically precise monolayer-protected gold thiolate nanoclusters are an intensely researched nanomaterial framework, but there is a lack of a system that can be directly synthesized and undergo interfacial surface chemistry.

Conditional Copper-Catalyzed Azide Alkyne Cycloaddition by Catalyst Encapsulation [PDF]
, 2020 Supramolecular encapsulation is known to alter chemical properties of guest molecules. Here we apply this strategy of molecular encapsulation to temporally control the catalytic activity of a stable Cu(I)-carbene catalyst.
