WitrynaIt has also been shown that in some cases the unstable organolithien can be trapped in situ by adding the lithic base to a mixture of arene and borate (Scheme 2). Limitations for the ortholithiation is that this synthesis must be done at very low temperatures (from -78°C to -40°C) with often, limited existing synthesis tools with which the ...

In organometallic chemistry, organolithium reagents are chemical compounds that contain carbon–lithium (C–Li) bonds. These reagents are important in organic synthesis, and are frequently used to transfer the organic group or the lithium atom to the substrates in synthetic steps, through nucleophilic addition or simple deprotonation. Organolithium reagents are used in industry as an initiator for a… WitrynaIn order to identify new inhibitors of the dengue virus (DENV) NS5 RNA polymerase, a screening was led on 650 new-caledonian plants.
