A one-pot synthesis of some novel anionic scaffolds: the substituted-4-((4-trimethylsilyl-1H-1,2,3-triazol-1-yl)methyl)-2H-chromen-2-one is reported. Reaction of 10 different substituted bromomethylcoumarins with trimethylsilylacetylene and sodium azide in the presence of copper(I) iodide catalyst gave the corresponding heteroaryl conjugates: the substituted-4-((4-trimethylsilyl-1H-1,2,3-triazol-1-yl)methyl)-2H-chromen-2-one in 70–92% yields. The structures of the synthesized compounds have been completely characterized by spectral and elemental analyses. For the first time, the representative single-crystal X-ray structure analysis of 6-methoxy-4-((4-trimethylsilyl-1H-1,2,3-triazol-1-yl)methyl)-2H-chromen-2-one is reported which confirms the formation of anionic synthon which bears the trimethylsilyl-group.

Abstract This work highlights the electrochemical applications of pyridinedicarboxylic acid based Cobalt metal-organic framework (Co-MOF). Cobalt metal-organic framework (Co-MOF), as-synthesized was characterized by the techniques such as ATR-IR, PXRD, SEM, Single crystal XRD, and BET. The Co-MOF electrode was prepared and electrochemical performance was carried out to explore sensing activity of the material for Glucose. The electrochemical sensing experiments were performed in acetate buffer and phosphate buffer separately. An excellent response obtained by the Co-MOF electrode for sensing the Glucose at very low concentrations in acetate buffer. [ABSTRACT FROM AUTHOR]
