Convenient Titration Method for Organometallic Zinc, Magnesium, and Lanthanide­ Reagents

Abstract

A convenient and reliable procedure for the titration of various organometallic compounds, such as magnesium, zinc, and lanthanides by using 0.5 M THF solutions of LiCl as the titration medium has been developed.

Key words

titration - magnesium reagents - zinc reagents - organolanthanide reagents - lithium chloride

It is possible to determine the concentration of most organolithium compounds using our procedure with the exception of some secondary and tertiary alkyl lithiums in which a facile elimination of HI from the alkyl iodide formed during titration is possible (for example s-BuLi and t-BuLi).
