Technology Process of Pyrophosphoryl tetrafluoride

There total 2 articles about Pyrophosphoryl tetrafluoride which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 34.1%

difluorophosphoric acid (13779-41-4) + trichloro(o-phenylenedioxy)phosphorane (2007-97-8) → o-phenylene chlorophosphate (1499-17-8) + difluorophosphoric acid anhydride (14456-60-1) + phosphorus oxydifluorochloride (13769-75-0)

Guidance literature:

byproducts: HCl; HOP(O)F2 droped to C6H4O2PCl3 at -78°C, warmed; ClP(O)F2 condensed on cooling, distilled under vacuum at 41°C/12.0 kPa, distilled fractionally at normal pressure, NMR, elem. anal.;

Reference yield:

silver hyponitrite + difluorophosphinic bromide (14014-18-7) → bis-difluorophosphinic hyponitrite + difluorophosphoric acid anhydride (14456-60-1) + dinitrogen monoxide (10024-97-2)

Guidance literature:

In neat (no solvent); byproducts: AgBr; performed in the absence of light; F2P(O)Br condensed into a Fisher-Porter tube charged with silver hyponitrite; warmed to room temp. and left for 2 h; product passed through traps: the -78 and -130°C trap contained amixture of F2P(O)Br and F2P(O)OP(O)F2, the -196°C trap contained N2O;
