Dioxides of <i>C</i>‐Amino‐Substituted Phosphaalkenes and Phosphaallyl Cations

Abstract

Reaction of the phosphaallyl cation 1 with oxygen transfer agents is reminiscent of enamine epoxidations and the ring-opening of amino-oxiranes. Even the perchlorate counterion can effect this oxidation in acetonitrile at 60 °C. No kind of conjugation between the two amidinio moieties is detectable in the product 2.
