Technology Process of Bis-difluorophosphinic oxide

There total 4 articles about Bis-difluorophosphinic oxide 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:

silver hyponitrite + bromodifluorophosphine (15597-40-7) → μ-oxo-bis(difluorophosphane) (13812-07-2) + hyponitrite(difluorophosphine)2 + dinitrogen monoxide (10024-97-2)

Guidance literature:

In neat (no solvent); byproducts: AgBr; performed in the absence of light; silver hyponitrite placed in a Fisher-Porter tube wrapped in aluminum foil; F2PBr gas condensed into the tube; mixture warmed to room temp. and kept for 2 h; product passed through traps: the -130°C trap contained a mixtureof F2PBr and F2POPF2, the -160°C trap contained N2O;

DOI:10.1021/jp045984j

Reference yield:

difluorophosphino(disilyl)amine (71579-71-0) + water (7732-18-5) → disiloxane (107-46-0) + aminodifluorophosphine (25757-74-8) + μ-oxo-bis(difluorophosphane) (13812-07-2) + difluoro(silylamino)phosphine (36875-96-4) + trifluorophosphane (7783-55-3)

Guidance literature:

In chloroform-d1; absence of air and moisture; room temp.; not isolated, reaction followed by (1)H- and (31)P-NMR spectroscopy; further products: SiH4, SiFH3;
