Lithiating

Web15 jul. 2005 · It is the purpose of this chapter to survey and classify the vast accumulation of heteroatom-facilitated lithiations recorded since the first coverage in Organic Reactions. As outlined by Gilman and Morton, the terms “metalation” in general and “lithiation” in particular denote any replacement of a hydrogen atom by metal or lithium. WebLithiated carbon All the investigations that have been performed so far suffer from the fact that the deprotonation of the imines by strong bases gives metalation—after which an electrophilic reaction takes place on the less substituted a-carbon. Lithiation that does not depend on the degree of substitution on the a-carbon was developed by Wender and co …

WebRutile-type titanium oxide (TiO2) is a resource-rich and inexpensive material with a one-dimensional ion-diffusion path along the c-axis. However, it has received no attention as an anode material for Na-ion batteries because of its low electronic conductivity and limited ion diffusion in the ab-plane direction. We have revealed for the first time the reversible Na … WebFor this reason, they used LDA as the lithiating agent, which led to the formation of two regioisomeric ArLi species. The ability to track the interconversion of these two isomers via ReactIR enabled the identification of the optimum set of reaction variables to ensure the formation of the thermodynamically preferred 3-Li species.

WebThis paper compares and combines two common methods to improve the cycle performance of lithium metal (Li) electrodes. One technique is to establish a micro-structured current collector by chemical separation of a copper/zinc alloy.
