✦ Synopsis

Poly)alkoxymethylphosphine oxides were synthesized by the Williamson reaction starting from (poly)hydroxymethyl or (poly)chloromethylphosphine oxides. For the first time, the use of phase transfer catalysis for the synthesis of (O)PCOC bridges is demonstrated.

Terminal olefins can be converted to ketones in good yields, and under mild conditions, using phase transfer catalysis; the water-nary ammonium salt governs thecourseof the reaction. Many applications of phase transfer catalysis in organic chemistry have been described in the literature during the p
