Abstract

A series of 11 amino acid-derived stabilised ylides 12–14 and 16 have been prepared and characterised. In one case, for compound 17, an X-ray structure determination supports formulation of the compounds as phosphonium enolates. Flash vacuum pyrolysis (FVP) of 12 and 13 at 500° C results in loss of RPO between the
