Zhang, Yong-Gang published the artcilePalladium/Copper-Catalyzed Oxidative Arylation of Terminal Alkenes with Aroyl Hydrazides, SDS of cas: 4141-48-4, the publication is Chemistry – A European Journal (2014), 20(10), 2765-2769, database is CAplus and MEDLINE.

An unprecedented oxidative arylation reaction of terminal alkenes with simple aroyl hydrazides has been developed under aerobic conditions for a stereoselective synthesis of 1,2-disubstituted alkenes. A range of aroyl hydrazides underwent palladium/copper-catalyzed oxidative Mizoroki-Heck reaction with terminal alkenes open to air in a 1:1 mixture of DMSO and acetonitrile to give structurally diverse 1,2-disubstituted alkenes in moderate to excellent yields with excellent regio- and E-selectivity. The reaction tolerated a wide variety of functional groups, such as alkoxy, hydroxy, amino, fluoro, chloro, bromo, cyano, nitro, ester, amide, imide, phosphine oxide, and sulfone groups, and, moreover, mol. oxygen and DMSO were demonstrated to serve as terminal oxidants. This study provides a useful method for the stereoselective synthesis of 1,2-disubstituted alkenes by a direct transformation of the vinylic carbon-hydrogen bonds (C-H bonds) in terminal alkenes.

The efficient and regioselective hydrosilylation of epoxides co-catalyzed by a pentacarboxycyclopentadienyl (PCCP) diamide Ni complex and Lewis acid is reported. This method allows for the reductive opening of terminal, monosubstituted epoxides to form unbranched, primary alcs. A range of substrates including both terminal and nonterminal epoxides work, and a mechanistic rationale is provided. This work represents the 1st use of a PCCP derivative as a ligand for transition-metal catalysis.

Coscia, Rockford W. published the artcileDevelopment of a formal [4 + 1] cycloaddition: Pd(OAc)₂-catalyzed intramolecular cyclopropanation of 1,3-dienyl ¦Â-keto esters and MgI₂-promoted vinylcyclopropane-cyclopentene rearrangement, COA of Formula: C15H15OP, the publication is Journal of the American Chemical Society (2009), 131(7), 2496-2498, database is CAplus and MEDLINE.

A formal [4 + 1]-cycloaddition of 1,3-dienyl ¦Â-keto esters has been developed. This two step process involves Pd(II)-catalyzed intramol. cyclopropanation to produce vinylcyclopropanes, e.g., I, and a subsequent mild vinylcyclopropane-cyclopentene rearrangement promoted by MgI₂. The cyclopropanation method notably requires the use of Mg(ClO₄)₂, presumably to facilitate keto-enol tautomerization, and is greatly improved by the use of copper(II) isobutyrate as co-oxidant. A range of substrates with various substitution patterns is demonstrated.

Padwa, Albert published the artcileRhodium(II)-catalyzed cyclization reactions of alkynyl-substituted ¦Á-diazo ketones, Safety of Allyldiphenylphosphine oxide, the publication is Journal of Organic Chemistry (1991), 56(7), 2523-30, database is CAplus.

Treatment of several o-alkynyl-substituted ¦Á-diazoacetophenone derivatives with rhodium(II) carboxylates results in the formation of substituted indenones. The simplest mechanism accounting for the results involves addition of a rhodium-stabilized carbenoid onto the acetylenic ¦Ð-bond to generate a vinyl carbenoid directly or possibly a highly strained cyclopropene derivative The vinyl carbenoid was found to undergo addition to a neighboring alkene tethered on the side chain to give an indenyl-substituted bicyclo[3.1.0]hexane derivative A number of related systems were examined so as to probe the scope and generality of the process. Treatment of 2-[CH₂:CHCH:CH(CH₂)₃Cú·C]C₆H₄COCHN₂ with rhodium(II) mandelate afforded a benzocyclopent[g]azulenone derivative I. The formation of this compound involves a divinylcyclopropane intermediate that readily undergoes a Cope rearrangement under the reaction conditions. The rhodium-catalyzed reaction of 2-[MeCO(CH₂)₃Cú·C]C₆H₄COCHN₂ in the presence of N-phenylmaleimide afforded a mixture of two cycloadducts II and III. Product II can be accounted for in terms of a cyclization of the vinyl carbenoid onto the oxygen atom of the neighboring carbonyl group to give a resonance-stabilized dipole. 1,3-Dipolar cycloaddition of the carbonyl ylide across the activated ¦Ð-bond of N-phenylmaleimide affords the observed product. The structure of II was confirmed by x-ray anal. The second cycloadduct III is formed by a 1,2-hydrogen shift of the initially produced vinyl carbenoid. The resulting diene undergoes a subsequent Diels-Alder reaction with N-phenylmaleimide.

Reaction of the trimethylsilyl (TMS) enol ethers, e.g. I, derived from the conjugate addition of organo-copper reagents to 3,4-dimethylcyclopentenone with di-Me dioxirane (DMDO) leads to ¦Á-hydroxy ketones with predominantly the syn-Me orientation. Exposure of these systems to methanolic lead tetraacetate (Pb(OAc)₄) delivers aldehydic esters which are homologated to the desired E-dienes, e.g. II, using Yamamoto’s allylic phosphine oxide reagent.

The angular tricyclopentanoid sesquiterpene (¡À)-3-oxosilphinene (I) was stereoselectively prepared with an intramol. Diels-Alder reaction as the key step. On heating, the (E,E)-sulfenyltriene II (R = CHMeCH₂CH₂CH:CHCH:CHSPh), derived from II (R = Br) gave only 1 stereoisomer of tricyclo[7.3.0.0^1.5]dodecene III having all 4 contiguous asym. centers with the required stereochem. The cycloadduct III was converted into the racemate of I via ring contraction.

In this work, UV-radiation curing of allyldiphenyl phosphine oxide (ADPPO) and 4,4′-bis(allyloxyphenyl) Ph phosphine oxide (DAPPO) monomers with epoxy acrylate resin in the presence of a photoinitiator was studied and their flame-retardant performance compared with pure epoxy acrylate film. The structures of allyl functional phosphorus compounds were characterized by FT-IR, ¹H NMR, ¹³C NMR and all spectra were consistent with the expected structures. The polymerization behavior of both allyl functional monomers was followed in detail by monitoring the disappearance of acrylate and allyl groups by real-time IR spectroscopy. The reactivity of DAPPO monomer is higher than ADPPO. In the case of ADPPO, chain transfer to monomer basically predominates. In each monomer, a tack free coating was obtained immediately upon irradiation The addition of DAPPO leads to an improvement of the thermal and flame-retardant properties of the polymeric films. Thermal gravimetric anal. of DAPPO containing polymeric films gave higher char yield compared with UV-cured pure epoxy acrylate resin.
