We report a redox-neutral P(O)–N coupling reaction of P(O)–H compounds with azides via photoredox and copper catalysis, providing new access to useful phosphinamides, phosphonamides, and phosphoramides. This transformation tolerates a wide range of nucleophilic functionalities including alcohol and amine nucleophiles, which makes up for the deficiency of classical nitrogen nucleophilic substitution
Diphenylphosphinic amides and diphenylphosphine oxides have been synthesized and tested as inhibitors of the Kv1.5 potassium ion channel as a possible treatment for atrial fibrillation. In vitro structure-activity relationships are discussed and several compounds with Kv1.5 IC50 values of <0.5 mu M were discovered. Selectivity over the ventricular IKs current was monitored and selective compounds were found. Results from a rabbit PD-model are included. (c) 2012 Elsevier Ltd. All rights reserved.

Twonew Ag(I) complexes of N-(n-pyridinyl)diphenylphosphinic amide (n = 2 and 3) (Lo and Lm) with formulae Ag(Lo)NO3 (Co) and Ag(Lm)NO3·H2O (Cm) were synthesized. Infrared, NMR, and elemental analyses were applied to fully characterize them. The crystal structure of Cm was also assessed using single-crystal X-ray diffraction and the monoclinic nature of the silver complex was illustrated. The organization
