ArMgX
ArMgX refers to arylmagnesium halides, a class of Grignard reagents used in organic synthesis. The general formula is Ar-Mg-X, where Ar is an aryl group and X is a halogen (typically Cl, Br, or I). These reagents are highly reactive, moisture- and air-sensitive, and they form solvated complexes with ether solvents such as diethyl ether or THF.
Preparation and structure occur by transferring magnesium metal into an anhydrous solution of an aryl halide
Reactivity and key transformations include: reaction with carbon dioxide to yield the corresponding carboxylic acid after
Representative examples include phenylmagnesium bromide (PhMgBr) and p-tolylmagnesium chloride (p-MeC6H4MgCl). Practical use requires strictly dry conditions,
