Abstract

Highly coloured paramagnetic polymer supported lithium 5,5′ and sodium 6,6′ naphthalenide complexes have been prepared from the reaction of THF solutions of lithium and sodium biphenylide with polystyrene bearing -CH2SiMe2(C10H7) groups. Treating chloropropyl functionalised silica, alumina and titania surfaces with H3Al · NMe3 or H3Ga · NMe3 afford hydroxyl depleted surfaces. Successive treatment with lithium biphenylide, 1-(chlorodimethylsilyl)naphthalene and an alkali biphenylide affords supported alkali naphthalenide complexes which generate in high yield lithium and sodium reagents when treated with a range of organic halides, nitriles and phosphates, as found for 6,6′ and 7,7′.
