Co-ordination studies of polyarene and halocarbon functionalised tertiary phosphines for explosives detection by Thomas A. Noble

“…Subsequent reduction yielded new PAH‒substituted amines and the Mannich‒based condensation chemistry of these new amines was explored using HOCH2PR2 precursors to yield (9‒anth)CH2N(R)CH2X (X = PAd or PR’2) ligands.
