Hydroxyethylphosphonate dioxygenase (HEPD) catalyzes the O 2-dependent cleavage of the carbon-carbon bond of 2-hydroxyethylphosphonate (2-HEP) to afford hydroxymethylphosphonate (HMP) and formate without input of electrons or use of any organic

Hybrid materials that are composed of a polymeric material interfaced with an inorganic, metal oxide material have been a rapidly expanding research area in the last few decades. However, interfacial regions remain an important area of focus, and as such hybrid materials do not always possess a very robust or stable interface. Tailor-made interfacial molecules have been successfully reported but material scientists wishing to develop composite interfacial materials would favorably use commercial solutions. Our study shows how we can leverage a commercially available organophosphonic acid group that is coupled with a 2-bromo isobutyrate initiator for surface initiated atom transfer radical polymerization (SI-ATRP) for use as a strong interfacial molecule. We illustrate this mechanism with both nanoparticles of titania and flat titania substrates used as the grafting support and polymerization anchoring points. We demonstrate that the size of the organophosphonic acid initiator, specifically the carbon spacer between the reactive groups, controls the stability of the molecule. The actual covalent linkage between the phosphonic acid group and the titania surface while also leaving the ATRP initiating group able to start the polymerization, is confirmed via31P solid state NMR spectroscopy, liquid 1H NMR spectroscopy XPS, DLS and SEM.
METHOD FOR THE MANUFACTURE OF COMPOUNDS CONTAINING AN ALPHA-OXYPHOSPHORUS GROUP BY USING AN ACTIVATOR

Page/Page column 41, (2013/03/26)
A method for the manufacture of compounds containing an a-oxy phosphorus group is disclosed. A compound containing an a-oxy carboxylic acid group is reacted in a specific equivalent ratio with a nucleophilic P component, wherein the phosphorus atom has the oxidation state +1 or +3, whereby the compound containing an a-oxy carboxylic acid group or the nucleophilic P component or both are first reacted with an activator, followed by conducting the reaction and adding a water at the end of the reaction. The compounds containing an a-oxy phosphorus group formed are then recovered.

Page/Page column 45, (2012/08/07)
A method for the manufacture of compounds containing an α-oxy phosphorus group is disclosed. A P-O component having at least one P-O-P moiety, whereby at least one phosphorus has the +3 oxidation state, is added in specific proportions to a compound containing an α-oxy carboxylic acid group, followed by conducting the reaction and adding water subsequently. The compounds containing an α-oxy phosphorus group formed can then be recovered.
