Surface protection of copper by self-assembly of novel poly(5- methylenebenzotriazol-N-yl)

The novel polymer poly(5-methylenebenzotriazol-N-yl), denoted BTA-poly, was investigated for the protection of copper by electrochemical studies and weight loss measurements. The electrochemical measurements were compared to weight loss measurements and satisfactory results were obtained. Compared with benzotriazole, which is one of the best corrosion inhibitors for copper, BTA-poly achieves good protection under the same test conditions. Due to the rapid adsorption of BTA-poly onto copper, its corrosion-inhibition efficiency can be controlled by varying the concentration. The protecting effects of the polymers were studied in a sodium chloride solution using electrochemical measurements and an immersion test. The surface characteristics of the polymer-modified copper were analyzed via X-ray photoelectron spectroscopy (XPS), and scanning electron microscopy (SEM). These results show that BTA-poly can be easily adsorbed onto the copper surface via self-assembly to achieve excellent anticorrosion/antioxidation effects.

Blue-light-promoted radical C-H azolation of cyclic nitrones enabled by Selectfluor

An original approach to achieve the C(sp2)-H azolation of cyclic aldonitrones mediated by Selectfluor has first been employed. By exploiting a metal-free, visible-light-promoted cross-dehydrogenative C-N coupling reaction between model aldonitrones, 2H-imidazole 1-oxides, and NH-containing azoles, a series of novel azaheterocyclic derivatives have been obtained in yields up to 94%. The elaborated protocol has proved to be appropriate for gram-scale processes and displayed potential for utilization in the synthesis of novel structural analogues of lanabecestat. Besides, mechanistic studies have revealed that this coupling reaction is likely to proceedviaa nitroxide-involving radical pathway, encompassing a chain of electron transfer events, such as hydrogen atom transfer (HAT) and single electron transfer (SET).

The discovery of new scaffold of plant activators: From salicylic acid to benzotriazole

Started from salicylic acid (SA) and related commercialized plant activators, based on molecular three-dimensional shape and pharmacophore similarity comparison (SHAFTS), a new lead compound benzotriazole was predicted and a series of benzotriazole derivatives were designed and synthesized. The bioassay showed that benzotriazole had high activity against a broad spectrum of diseases including fungi and oomycetes in vivo, but no activity in vitro. And the introduction of proper groups at the 1’-position and 5’-position was beneficial to the activity. So, they had the potential to be exploited as novel plant activators.
