✦ Synopsis

Mechanism of the Stevens Rearrangement of Ammonium Ylides. -The title rearrangement of the ylide precursor (I) is studied, revealing that the Stevens rearrangement occurs at room temperature. The isomerization to compound (II) is always accompanied by formation of the Sommelet-Hauser rearrangement product (III). The reaction mechanism is discussed. -(MAEDA,
