PDF The Historical Development of MechanochemistryFriscic Group Projects McGill University

This paper reviews the history of mechanochemistry It begins with prehistoric times when reactions could be initiated during grinding and rubbing accidentally and follows the main developments Recently we describe the first application of mechanochemistry to conduct a fundamental transformation of organometallic chemistry oxidative addition1 By using simple organometallic rhenium I precursors as model compounds we have demonstrated for the direct oxidative addition of halogens Cl Br and I onto a metal centre via a mechanochemical procedure that unlike all relevant
