Benzylic Grignardreagents (2)–(4), bearing ortho- and para-halogeno ring substituents, are readily accessible by treating the corresponding benzylic halide with [Mg(anthracene)(thf)3](1) in tetrahydrofuran (thf); o- and p-chloromethyl(methoxymethyl)benzenes with (1) rapidly yield ‘di-Grignards’ whereas the meta-isomer only affords a mono-Grignard' (5), and bis(methoxymethyl)benzenes slowly undergo
