Reactions of Elemental Phosphorus and Phosphines with Electrophiles in Superbasic Systems: XII.~1 Synthesis of Unsymmetrical Teriary Phosphine Oxides from Red Phosphorus and Organyl Halides

摘要

Alkyldibenzyl-and benzyldialkylphosphine oxides were prepared in one stage by direct phsophorylation of a mixture of alkyl bromides and benzyl chloride with red phsophorous under the conditions of phase-transfer catalysis (concentrated aqueous KOH solution-dioxane-benzyltriethylammonium chloride).
