グリニャール試薬の生成機構：単電子移動とラジカルの役割

Textbooks omit the curly arrows: Grignard reagent formation involves single-electron transfers and radicals

Abstract: Grignard reagents form when alkyl halides react with magnesium through a radical mechanism initiated by single-electron transfer (SET). This article explains the stepwise electron flow and evidence for radical intermediates, highlighting insights from Walborsky (1990) and Garst (1997) often left out of textbooks.
