Free radical reaction of α-haloalkylphosphonates with alkenes and alkynes: A new approach to modified phosphonates

A new approach to the synthesis of phosphonates 3 functionalized in the α- and γ-phosphonate positions by alkyl, ethoxy, butoxy, acetoxy, acetyl and cyanide groups and allylphosphonate 6 is described. It is based on the radical reaction of α-halosubstituted phosphonates 1 (X = Cl, Br, I) with the terminally unsubstituted alkenes 2 (1-heptene, ethoxyethene, butoxyethene, acetoxyethene, acrylonitrile, methyl vinyl ketone) and alkyne 5 (hept-1-yne). The reaction involving the tin hydride method (Bu3SnH/AIBN) was more effective with alkenes than with alkynes (40-72% versus 20-30%). With electron-rich alkenes, chloro- and bromomethylphosphonates 1 (X = Cl, Br) gave higher yields than iodomethylphosphonate 1 (X = I). Diethyl methylphosphonate 4, as a reduction product of 1, accompanied 3 and 6 in the above reactions. The yield of 4 could be reduced by optimizing the reaction conditions.

Consecutive approach to alkenes that combines radical addition of phosphorus hydrides with horner-wadsworth-emmons-type reactions

(Chemical Equation Presented) Addition of diethyl thiophosphite to terminal alkenes, in the presence of a radical initiator, followed by deprotonation of the phosphonothioate and reaction with a ketone, offers a concise one-pot approach to substituted alkenes. This novel method, which can incorporate alkylation or acylation steps, can be applied to the stereoselective formation of sterically hindered tri- and tetrasubstituted alkenes.

A solution-based approach to composite dielectric films of surface functionalized CaCu3Ti4O12 and P(VDF-HFP)

High permittivity CaCu3Ti4O12/ poly(vinylidenefluoride-co-hexafluoropropylene) P(VDF-HFP) nanocomposites were investigated as dielectrics for film capacitors. CaCu3Ti 4O12 was synthesized by two different soft-chemistry methods, namely, decomposition of a citrate precursor and a recently developed lactate precursor to identify a preferable route to nanometer scale spherical particles with an increased interfacial area. A ball-milling step was applied to break particle agglomerates and to enhance particle distribution in the composite films. To improve the wetting of the CaCu3Ti 4O12 oxide particles and the polymer, a variety of surfactants, e.g. carbonic acid, silane, sulfonic acid and phosphonic acid were investigated. A successful oxide surface functionalization was achieved by 2,3,4,5,6-pentafluorobenzyl phosphonic acid, leading to stable bonds and good structural compatibility between the surfactant and the highly fluorinated polymer matrix. The films were prepared from composite dispersions by a spin-coating technique and can be formed out of powders from both precursors, but the citrate method is preferable due to milder synthesis conditions and improved film homogeneity. The use of ball-milled powders as the oxide component results in homogeneous particle distributions even near to the percolation threshold. In addition, such fine-ground particles lead to homogeneous film thickness and decreased film roughness. Dielectric measurements at different frequencies revealed an enhancement in the relative permittivity by a factor of 5 compared to the pure polymer while the dielectric losses remained very low.

The synthesis was performed by reaction of alkylphosphonic acids with choline derivatives in the presence of 2,4,6-triisopropylbenzenesulfonyl chloride. The micellar, surface active, and solubilization properties of new surfactants were studied. Antiprotozoal activities were tested against Acanthamoeba lugdunensis and Acanthamoeba quina.

Generation of phosphorus-centered radicals via homolytic substitution at sulfur

(Chemical Equation Presented) A novel radical domino process relying on the homolytic cleavage of P-S bonds allows the preparation of phosphorus-containing molecules through addition of P-centered radicals onto olefins. The key step of this reaction is a homolytic substitution on a sulfur atom. The scope of the reaction is broad. Diaminophosphonyl radicals whose reactivity was unknown react smoothly with olefins. Use of tin hydride can be avoided. A radical thiophosphinoylation of triple bonds has been uncovered.
