Phosphine oxide - Wikipedia

WebPhosphine oxide are typically produced by oxidation of organophosphines. The oxygen in air is often sufficiently oxidizing to fully convert trialkylphosphines to their oxides at room temperature: R 3 P + 1/2 O 2 → R 3 PO This conversion is usually undesirable. WebIn this research we have chosen phosphine oxide based reactive moiety to construct the polyimides. Compared to other phosphorus chemistries, the choice of phosphine oxide moiety has obvious advantages. P–C bond (compared to P–O–C)15 and P]O bond (compared to phosphine) offer hydrolytic and oxidative stability, respectively. the horse network https://kabpromos.com
