- A practical method for N-alkylation of phosphinic (thio)amides with alcohols via transfer hydrogenation
-
This manuscript describes a modular method for preparing N-alkyl phosphinic amides from primary or secondary alcohols and primary phosphinic amide (R1R2P = ONH2) nucleophiles via transfer hydrogenation. The transformation typically proceeds in excellent yields, employs conveniently available reagents, and produces water as the only byproduct.

- Iridium Supported on Phosphorus-Doped Porous Organic Polymers: Active and Recyclable Catalyst for Acceptorless Dehydrogenation and Borrowing Hydrogen Reaction
-
Iridium-on-phosphorus-doped porous organic polymers (POP?Ir) were developed by anchoring simple iridium onto the skeleton of porous organic polymers through coordination bonds. This POP?Ir catalyst, which was thoroughly characterized by means of EDS, SEM, TEM, XRD, XPS, and FT-IR, revealed excellent catalytic activity for the reaction of diphenyl phosphinamide with benzyl alcohols through borrowing hydrogen strategy and acceptorless dehydrogenation with wide functional group tolerance. Moreover, this POP?Ir catalyst could be simply recovered and reused for at least five times without a significant loss of activity, and revealed considerable application prospects. The mechanism was investigated to further understand this POP?Ir catalytic system and transformations. Overall, the POP?Ir catalytic system has shown high activity and reusability in the borrowing hydrogen reaction between diphenyl phosphinamides and benzyl alcohols. (Figure presented.).
