Firouzabadi, Habib,Iranpoor, Nasser,Sobhani, Sara
, p. 1483 - 1491 (2004)
Various types of diethyl α-hydroxyphosphonates were converted efficiently to their corresponding diethyl α-ketophosphonates by pyridiinum chlorochromate (PCC) without cleavage of C(O) - P bond in the absence of solvent or in solution in high yields.
Surface-mediated solid-phase reactions: The preparation of acyl phosphonates by oxidation of 1-hydroxyphosphonates on the solid surface
Kaboudin, Babak
, p. 3169 - 3171 (2000)
Alumina-supported CrO3, under solvent-free conditions, was found to be an efficient oxidizing reagent for the preparation of acyl phosphonates from 1-hydroxyphosphonates. This method is an easy, rapid, and high-yielding reaction for the prepara

A simple strategy for yielding chiral tertiary α-hydroxy phosphonates that integrates two highly biologically relevant scaffolds namely 3-alkylidene-2-oxindoles and phosphonates has been described. The hydrogen bonding ability of the bifunctional thiourea catalyst allows simultaneous dual activation of a vinylogous oxindole nucleophile and an acylphosphonate electrophile, affording hydroxyphosphonato-3-alkylidene-2-oxindoles as aldol adducts in high yields (up to 92%) with excellent stereocontrol (up to 99% ee).
Visible photocatalysis of novel oxime phosphonates: Synthesis of β-aminophosphonates

A novel type of oxime phosphonate was synthesized and used in the intermolecular cascade radical addition reaction of alkenes to access β-aminophosphonates via visible-light-driven N-centered iminyl radical-mediated and redox-neutral selective C-P single-bond cleavage in an active phosphorus radical route. The procedure is characterized by its ability to achieve the construction of Csp3-P and Csp3-N bonds without the requirement for oxidants and bases.
