Cationic Copper Iminophosphorane Complexes as CuAAC Catalysts: A Mechanistic Study [PDF]
Organometallics, 2020 We have combined Cu K-edge X-ray absorption spectroscopy with NMR spectroscopy (1H and 31P) to study the Cu-catalyzed azide–alkyne cycloaddition (CuAAC) reaction under operando conditions. A variety of novel, well-defined CuI iminophosphorane complexes were prepared.

Polymeric Blatter's Radical via CuAAC and ROMP [PDF]
Macromolecular Chemistry and Physics, 2021 AbstractA Blatter radical‐containing polymer backbone is synthesized via copper‐catalyzed azide‐alkyne cycloaddition (CuAAC) and consecutive ring‐opening metathesis polymerization. For this, an alkyne‐functionalized Blatter radical is synthesized and used for the described CuAAC, yielding a polymerizable derivative of the radical. The resulting polymer

Carbohydrate CuAAC click chemistry for therapy and diagnosis
Carbohydrate Research, 2016 Carbohydrates are important as signaling molecules and for cellular recognition events, therefore offering scope for the development of carbohydrate-mimetic diagnostics and drug candidates. As a consequence, the construction of carbohydrate-based bioactive compounds and sensors has become an active research area. While the advent of click chemistry has

CuAAC reactions of sterically hindered azides
Visnyk of the Lviv University. Series Chemistry, 2020 The regularities of the CuAAC reactions due to the structure of the substituent were determined and basic requirements for the choice of the catalytic system in the case of azides or alkynes with bulky substituents, and azides containing fragments able to effectively act on Cu(I) ions were shown.
