Polymerization of allyl phenyl ether

Allyl phenyl ether polymerized rapidly and quantitatively to a resin with a structure similar to a phenolic thermoset in the presence of boron trifluoride etherate at 50°C. The structure and properties of this polyphenol were studied. A reaction mechanism involving rearrangement was discussed.     

Reaction of diphenylcarbodiimide with phenyl glycidyl ether

Conclusions The reaction of diphenylcarbodiimide with phenyl glycidyl ether gives 3-phenyl-5-phenoxymethyl-2-N-phenyliminooxazolidine, which, in contrast to a number of substituted iminooxazolidines, does not isomerize to the corresponding imidazolidinone when heated to 250°.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 2, pp. 474–476, February, 1983.     

Reaction of phenylbenzoxazole with phenyl glycidyl ether

Conclusions The reaction of phenyibenzoxazole with phenyl glycidyl ether is not limited to the addition of the -oxide ring to the C=N bond of phenyibenzoxazole, but is followed by addition of a second molecule of phenyl glycidyl ether with the formation of an N derivative of hydroxyaniline.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 6, pp. 1356–1359, June, 1987.     

对位取代苯基烯丙基醚的烷基化反应

烯丙基醚是一个重要的β-羰基化合物的合成等价物,已有许多应用,它的应用和反应的区域选择性有密切关系.最近,Werstiuk 曾对烯丙基化合物的反应及其在合成上的应用作了综述,并讨论了立体因素对烯丙基化合物反应区域选择性的影响.Evans 等研究了烯丙基烷基醚阴离子和亲电试剂反应中位阻和区域选择性的关系.当亲电试剂是卤代烷时,烯丙基醚中烷基体积增大,γ位烷基化的比例也增大;而亲电试剂为羰     

A study of the decomposition of field ionized doubly charged molecular ions

The dissociation of field ionized doubly charged organic molecular ions into doubly charged fragment ions and neutral fragments is discussed. The kinetic energy released during the dissociation of the singly and doubly charged molecular ions rules out the possibility of a direct correlation between their mechanisms of formation. Further, the pressure as well as the temperature dependence revealed that the singly charged molecular ions are formed by direct ionization of the neutral molecules, while the doubly charged molecular ions are formed through a second ionization process of the adsorbed molecular ions on the field anode surface.     

Water loss from molecular protonated ions of benzyl 2-phenylethyl ether and derivatives

The skeletal rearrangement for water loss is the dominant ion reaction in the chemical ionization mass spectrum of benzyl 2-phenylethyl ether. Isotopic distributions obtained for this reaction with specifically labelled derivatives have been interpreted in terms of competing five- and six-centred skeletal rearrangements. Chemical substitution of the alternative aromatic rings strongly influences the balance of the competition.     

Radical steps in diethyl ether decomposition

The thermal decomposition of diethyl ether was studied in the temperature range 697.2–760.5 K. The rate constant of reaction (1), and the ratio of the rate constant of reaction (2) to that of (12): were calculated from the amounts of products:      

Mechanism of reaction of phenyl glycidyl ether with phenyl benzoate in the presence of water

The reaction of phenyl glycidyl ether with phenyl benzoate in the presence of water was investigated by adsorption liquid chromatography.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 1, pp. 131–133, January, 1990.     

Reactions of 2-aminobenzothiazoles with phenyl glycidyl ether

In acidic media 2-aminobenzothiazole and its derivatives react with phenyl glycidyl ether at the ring nitrogen atom, while in alkaline media they react at the exocyclic nitrogen atom. The structures of the compounds were proved by spectral methods and alternative synthesis.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 5, pp. 685–691, May, 1991.     

Reaction of phenyl glycidyl ether with triphenyl isocyanurate

Conclusions On the example of the reaction of triphenyl isocyanurate with phenyl glycidyl ether it was shown that oxirane rings when heated can react with the isocyanurate ring to give oxazolidone fragments.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 7, pp. 1645–1646, July, 1981.
