“…The –N 3 peak at 2068 cm −1 increases obviously, suggesting that click reaction on copper surface is not fully reacted 47 . As for FT‐IR of Cu (CuDs + TA + BA) , the peaks of C═C at 1727 cm −1 , 48 C═N at 1591 cm −1 , and N═N at 1312 cm −1 are 49 characteristic peaks of triazole rings, indicating the presence of CuDs improves the formation of triazole film on copper surface 50 …”

The triazole inhibitive film was assembled on copper surface via the click reaction between p‐toluenesulfonyl azide (TA) and propiolic acid (PA) in presence of Cu2S quantum dots (CuDs). The click‐assembled film on copper surface has good anticorrosion property in 3 wt.% NaCl solution. The best protective efficiency is 93.7%. The role of CuDs for the click assembly is investigated by the spectral analysis, electrochemical measurements, and surface morphology characterization. The Cu(I) in CuDs exhibited good thermodynamic stability and catalytic activity. During the assembly process, CuDs become the new interface of the click reaction and facilitate the formation of the triazole inhibitive film on copper surface.

Copper–Bispidine Complexes: Synthesis and Complex Stability Study

et al. 2016

A new series of dicarboxylic derivatives of bispidines have been synthesized to develop novel copper(II) complexes suitable as imaging agents for positron emission tomography. For characterization purposes, copper complexes of bispidines were synthesized in the pure form and in quantitative yields by neutralization of ligands with malachite. The formation of complexes and their stoichiometries were studied by potentiometric titration, cyclic voltammetry, and spectroscopic methods. The stability constants were found to be fairly suitable for copper cation fixation inside dianionic chelate molecules.

“…The diazocine scaffold is present in several classes of important compounds in various fields of chemistry. Examples are Tröger's base derivatives and bispidines that are methylene‐bridged diazocines and have been extensively used in supramolecular chemistry . C‐curarine‐I, the most abundant, and probably the most important, of the calabash curare alkaloids possesses an oxo‐bridged diazocine nucleus .…”

Dimerization of 2‐(diformylmethylene)‐3,3‐dimethylindole by the action of tosyl chloride (TsCl) led to the creation of an epoxy‐[1,5]‐diazocine bicycle. The structure of the molecule resembles that of the naturally occurring C‐curarine‐I. The molecule shows significant cytotoxicity against cancer lines MCF‐7 and MDA‐MB‐231, but not toward the normal cell line CCD‐841. A series of substituted 2‐(diformylmethylene)‐3,3‐dimethylindoles was accordingly dimerized, and the products were studied for their cytotoxic activities.
