The present invention is related to a method for the synthesis of a heterocyclic hydrogen phosphine oxide, having the general formula (I), wherein: - R is a aliphatic or aromatic divalent group optionally comprising one or more heteroatoms and optionally comprising one or more substituents and - X and Y are independently selected from -O-, -C(O)O- and -NR'- wherein R' is a monovalent group optionally comprising one or more heteroatoms comprising the steps of: a) forming a reaction mixture by mixing a compound having the general formula HX-R-YH and tetraphosphorus hexaoxide; b) recovering the resulting compound comprising the heterocyclic hydrogen phosphine oxide.
