Synthesis of carboxylate phosphabetaines from 3-(diphenylphosphino)propanoic acid and unsaturated monocarboxylic acids

Post-polymerisation modification of poly(3-hydroxybutyrate) (PHB) using thiol–ene and phosphine addition

“…28,29 Galkin and co-workers reported on the functionalisation of unsaturated carboxylic acids using phosphines. [30][31][32][33][34] In particular, Bu 3 P has been described to form an irreversible acid-phosphine adduct.…”
