✦ Synopsis

Ylides derived from w-azidoalkyltriphenylphosphonium salts were generated at low temperature. They are stable at -80°C for several hours and react smoothly and stereospecifically with typical aldehydes to form Z-o-azido olefins which are the precursors of w-unsaturated primary and secondary amines.
