Abstract

Hydroxyl-depleted silica surfaces derived from treating chloropropylsilyl- (or chloropropylsilyl / trimethylsilyl-) functionalized silica with H3Al•NMe3 afford the corresponding organolithium reagent when treated with Li+(biphenyl)•-; successive treatment with 9-(chlorodimethylsily)anthracene and Mg(anthracene)(THF)3 generates anthracene and silica-supported “magnesium-anthracene”, which gives Grignard reagents of benzylic halides in tetrahydrofuran in excellent yield with the spent silica-supported anthracene being readily recycled.
