摘要：
Hydroxyl-depleted silica surfaces derived from treating chloropropylsilyl- (or chloropropylsilyl/trimethylsilyl-) functionalized silica with H3Al.NMe(3) afford the corresponding organolithium reagent when treated with Li+(biphenyl)(.-); successive treatment with 9-(chlorodimethylsilyl)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.
