General description

Phosphinic acid is a reagent containing P-H bond. Phosphinic acids (phosphinates) are the derivatives of phosphinic acid H₂P(O)(OH). Biochemical, biological, and medical applications of phosphinic acid compounds have been evaluated. Natural products containing carbon-phosphorus bonds (phosphonic and phosphinic acids) have wide applications in medicine and agriculture. Phosphinic acids have been synthesized via Michael addition of phosphonous acids as well as esters to activated conjugated systems. Phosphinic acid (Hypophosphorous acid) is an effective radical reducing agent for organic halides, thionoesters and isocyanides.

Biosynthesis of phosphonic and phosphinic acid natural products.

William W Metcalf et al.

Annual review of biochemistry, 78, 65-94 (2009-06-06)

Natural products containing carbon-phosphorus bonds (phosphonic and phosphinic acids) have found widespread use in medicine and agriculture. Recent years have seen a renewed interest in the biochemistry and biology of these compounds with the cloning of the biosynthetic gene clusters
