Alkyne-Substituted Deoxybenzoins as Precursors to Cycloaddition Chemistry and the Preparation of Low-Flammability Polymers and Blends

open access: yes, 2023
We report the synthesis and characterization of novel alkyne-substituted deoxybenzoins that are setup for azide–alkyne cycloaddition chemistry to yield oligomeric and polymeric structures that exhibit useful thermal properties, both on their own and as ...

Gamma Radiation Induced Contraction of Alkyne Modified Polymer Hydrogels [PDF]

open access: yes, 2021
We describe the gamma radiation induced crosslinking of alkyne-modified dextran polymer gels. Crosslinking of the alkyne moieties leads to gel contraction and fusion with other gel objects, and can be used for controlled ...

New catalytic strategies for DNA and RNA alkylation using rhodium (II) and copper (I) carbenes - a versatile tool for applications in chemical biology [PDF]

open access: yes, 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 ...

Electrochemical Hydroboration of Alkynes [PDF]

open access: yesChemistry – A European Journal, 2021
AbstractHerein we reported the electrochemical hydroboration of alkynes by using B2Pin2 as the boron source. This unprecedented reaction manifold was applied to a broad range of alkynes, giving the hydroboration products in good to excellent yields without the need of a metal catalyst or a hydride source.
