Structural and Electronic Control of the Bidentate 1‐(2‐pyridyl)benzotriazole Ligand in Copper Chemistry with Application to Catalysis in the A3 Coupling Reaction

“…On the basis of all these observations and bearing in mind that 1) Cu should simultaneously bind both nucleophile (phenylacetylide) and electrophile (imine), [23] 2) the benzotriazole entity can act as an acid or as a weak base [31, 32] and possibly form radicals, [31] 3) the reaction proceeds in the absence of additives, and 4) previous mechanisms based on Cu I or Cu II sources, [15–23] we propose the catalytic mechanism shown in Scheme 3. This mechanism has two interlinked pathways.…”

Partial Order–Disorder Transformation of Interpenetrated Porous Coordination Polymers

“…The same cluster and network topology have been reported in 3 PCPs based on similar bis-benzotriazolate ligands, including MFU-4, MFU-4l, and CFA-7. 27 The two crystallographically equivalent pcu nets in 2 interpenetrate parallelly, with one net residing at the midpoint of the cube defined by its partner (Figure 1). The shortest interatomic separations between the two nets are 7.2-9.0 Å (Supporting Information Figure S2).…”

“…24 The Kuratowski-type Zn 5 Cl 4 (Rvtz) 6 (Rvtz -= 1,2,3-triazolate group) clusters have a connection geometry the same as the classical Zn 4 O(RCOO) 6 (RCOO -= carboxylate group) clusters, which can be linked by linear backbones to form the NaCl-type networks. [27][28][29] Although the outer metal ions and end-capped chloride ions of the Zn 5 Cl 4 (Rvtz) 6 clusters can be readily exchanged, the metal-triazolate connections have much higher chemical stability compared with the metal-carboxylate connections. For example, [Zn 5 Cl 4 (bbta) 3 ] (MFU-4, H 2 bbta = 1H,5H-benzo(1,2-d:4,5-d')bistriazole) showed much higher water stability than [Zn 4 O(bdc) 3 ] (MOF-5, H 2 bdc = 1,4-benzenedicarboxylic acid), 29,30 and structural distortion or reconstitution has not been reported for these metal triazolate frameworks.…”

A Toughening and Anti‐Counterfeiting Benzotriazole‐Based High‐Performance Polymer Film Driven by Appropriate Intermolecular Coordination Force

“…Moreover, its coordination interaction is similar to that of the iron‐catechol system, while the coordination interaction with Cu 2+ is weaker than that of bipyridine/tripyridine ligands (see Supporting Information). [ 17–21 ] In this paper, we expect that the appropriate coordination interaction between BTA and Cu 2+ can be considered as a new dynamic cross‐linking, which can be deconstructed and reconstructed easily by the external forces, thus simultaneously improving the strength and extensibility for novel toughening high performance epoxy resins. To demonstrate the concept, series of Cu 2+ ‐polybenzotriazoles (PEPTDT‐Cu 2+ ) were prepared by a simple copolymerization of 1‐Epoxypropyl benzotriazole (EPT), triethylenetetramine, and bisphenol A diglycidyl ether (DGEBA) in the presence of Cu 2+ ( Figure ).…”
