Abstract
Abstract Phosphide anions, prepared by an action of sodium dihydridobis(2-methoxyethanolato)aluminate on derivatives of phosphine, phosphine oxide, or phosphorus esters, react with primary and secondary alkyl halides to produce phosphine derivatives having a newly formed phosphorus-carbon bond. The reactivity increases in the order of chloride<bromide<iodide and of secondary<primary in alkyl halide. Reaction of phosphide anion is also feasible with p-toluenesulfonate. Reaction of an anion of diphenylphosphine oxide seems to proceed mainly as an SN2 type process.
