TL;DR: In this article, the free-radical addition of alcohols to dimethyl maleate initiated by t-butyl peroxide was investigated and a method was developed for the synthesis of methyl 2-substituted paraconates in yields of 70-80%.
Abstract: 1.
An investigation was made of the free-radical addition of alcohols to dimethyl maleate initiated by t-butyl peroxide. On the basis of this reaction a method was developed for the synthesis of methyl 2-substituted paraconates in yields of 70–80%.
2.
The reactivities of unsaturated compounds in reactions with alcohols fall along the series; dimethyl maleate > methyl acrylate > allyl alcohol ≥ 1-alkenes.
3.
1-Hydroxyalkyl radicals formed from aliphatic alcohols are nucleophilic in character.

TL;DR: The reactions of trichloroethylene with toluene and with methanol, conducted 560-570°, leads to the formation of a mixture of the isomers R-CH=CCl2 and cis-and trans-R-CCl=CHCl (R=CH2C6H5 and CH2OH) as discussed by the authors.

TL;DR: The free-radical addition of the methyl ester and nitrile of 3-methoxypropionic add to alkenes, initiated with ditert-butyl peroxide, leads to the formation of 1:1 adducts which consist of methyl esters or nitriles of 2-alkyl-3methoxide, 3-alky-3 methoxy-, 3-alkyl-3-methyltimoxy-, and 3 -alkoxy substituted propionic acids.
Abstract: 1.
The free-radical addition of the methyl ester and nitrile of 3-methoxypropionic add to alkenes, initiated with ditert-butyl peroxide, leads to the formation of 1:1 adducts which consist of the methyl esters or nitriles of 2-alkyl-3-methoxy-, 3-alkyl-3-methoxy-, and 3-alkoxy substituted propionic acids.
2.
The reaction is accompanied by the formation of a small quantity of by-products produced by the partialβ-dissociation of the CH2OCH2CH2COOCH3 and CH3OCHCH2COOCH3 radicals.
TL;DR: In this paper, a series of chlorohydrocarbons, of interest as potential herbicides, was synthesized, of which trichlorovinyl group in the alkyl chain was used.
Abstract: 1.
As a result of the condensation of tetrachloroethylene with alkylaromatic hydrocarbons and chlorohydrocarbons in the gas phase at the temperature 420–570°, unsaturated chlorohydrocarbons with the trichlorovinyl group in the alkyl chain are formed.

A series of chlorohydrocarbons, of interest as potential herbicides, was synthesized.
TL;DR: In this article, the authors obtained 1∶1 adducts by the addition of acetic anhydride, malonic ester, propionic acid, and methyl monochloroacetate to 1-alkenes in the presence of tert-butyl hydroperoxide.
Abstract: 1.
The authors have obtained 1∶1 adducts by the addition of acetic anhydride, malonic ester, propionic acid, and methyl monochloroacetate to 1-alkenes in the presence of tert-butyl hydroperoxide.
2.
Initiation of addition is due mainly to the free radicals formed by thermal decomposition of tert-butyl peresters and tert-butyl hydroperoxide.
3.
tert-Butyl peresters are formed by acylation of tert-butyl hydroperoxide by carboxylic acids, their esters, and anhydrides.
TL;DR: In this article, conditions for the free-radical addition of N-acetyl amines to unsaturated compounds were worked out, and the effect of reaction conditions and the structure of the reactants on the ability of the latter to form 1∶1 adducts was studied.
Abstract: 1.
Conditions for the free-radical addition of N-acetyl amines to unsaturated compounds were worked out. This reaction can provide a preparative method for the synthesis of amines, including amines containing various functional groups.
2.
The effect of reaction conditions and the structure of the reactants on the ability of the latter to form 1∶1 adducts was studied, and it was shown, in particular, that this ability is the greater, the more highly electrophilic the double bond.
