Abstract

Abstract A convenient procedure for the quantitative assay of alkyl, aryl, and vinyl Grignard reagent concentrations is described. Through the combined use of menthol and 1,10-phenanthroline in dry tetrahydrofuran solution, vivid violet or burgundy end points materialize and are easily observed. Other advantages unique to the new protocol are also discussed.
