Lithium mesylate organic
Webknown as mesylates, occur widely in chemistry as esters or salts. Some of the organic derivatives are important biologically. This arises because mesylate is a good leaving group in nucleophilic substitution reactions as a result of the efficient delocalization of negative charge between the three oxygen atoms. Thus methyl- WebMesylates from QCI and QCD have proven to be an efficient intermediate for the preparation of halides, nitriles, phosphine, sulfur, and selenium derivatives. The halide …
