Abstract

Reaction of stable phosphinyl radical <b>1a</b> with AZADO gave aminoxyphosphine <b>3</b> as the primary product by selective radical coupling at −40 °C. Compound <b>3</b> decomposed to phosphorane <b>4</b>, silyl phosphinate <b>5</b>, and aminophosphine <b>6</b> at room temperature. The molecular structures of <b>4</b>–<b>6</b> were determined by X-ray structural analysis. The homolytic N–O bond cleavage of <b>3</b> and the subsequent silyl migration of the resulting phosphinoyl radical <b>7</b> would be key steps in the reaction.
