Chelating bond
WebCarbon-carbon bond activation refers to the breaking of carbon-carbon bonds in organic molecules. This process is an important tool in organic synthesis, as it allows for the formation of new carbon-carbon bonds and the construction of complex organic molecules. However, C–C bond activation is challenging mainly for the following reasons: (1) C-H … WebThe formation of these coordinate bonds involves the donation of electrons from functional groups of the chelating agent to the ion. In doing so, heterocyclic rings known as chelate …

WebThe purpose of this in vitro study was to evaluate the effect of various chelating solutions on the radicular push-out bond strength of calcium silicate-based and resin-based root canal sealers. Root canals of freshly-extracted single-rooted teeth (n = 80) were instrumented by using rotary instruments. The specimens were randomly divided into 4 ... WebFeb 17, 2024 · The chelating membrane exhibits a more excellent affinity to Pb(II) and Ni(II) than Ca(II), and thus, Pb(II) will remarkably interfere with the uptake of Ni(II). In addition, it can be deduced that the fabricated chelating membrane can be competent for removing heavy metals with a high biotoxicity from the aqueous solution.
