Conclusions The reaction of chlorine fluosulfate with acetylene leads mainly to the formation of 1,1-bis(fluorosulfonyloxy)-2,2-dichloroethane.Translated from Izvestiya Akademii Nauk SSSR Seriya Khimicheskaya, No. 10, pp. 2374–2376, October, 1981.     

Reaction of chlorine fluosulfate with perfluorocarboxylic acid nitriles

Conclusions The reaction of chlorine fluosulfate with perfluorocarboxylic acid nitriles, using an equimolar ratio of the reactants and the corresponding order of mixing them, gives N-chloroiminoperfluoroacyl fluosulfates in high yield, while the use of excess chlorine fluosulfate gives perfluoroacyl fluosulfates and pyrosulfuryl difluoride.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 10, pp. 2370–2373, October, 1981.     

Chlorination of some benzene derivatives by chlorine fluosulfate

Conclusions Exhaustive chlorination is observed when chlorine fluosulfate is reacted with 1,3,5-trichlorobenzene and nitrobenzene under mild conditions.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 5, pp. 1160–1161, May, 1982.     

Mass spectrometry of some fluorinated alcohols

The 70 eV electron impact mass spectrometric behaviour of some fluorinated alcohols, i.e. 2-fluoroethanol, 2,2,2,-trifluoroethanol, 2,2,3,3-tetrafluoropropan-1-ol and 1.3-difluoropropan-2-ol, was studied in detail by means of mass-analysed ion kinetic energy Spectrometry, deuterium-labelling experiments and comparison with unfluorinated analogues. Composite metastable peaks related to HF losses were rationalized by invoking the presence of two concurrent decomposition pathways, the first consisting in a 1,2-elimination and the second requiring the implication of hydroxyl hydrogen. This last process and other decomposition routes suggest the presence of H. bridging between the hydroxyl oxygen atom and fluorine.     

Reaction of iodine fluosulfate with fluoroolefins

Conclusions When reacted with fluoroolefins, iodine fluosulfate exhibits less expressed electrophilic properties than chlorine fluosulfate.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 10, pp. 2376–2379, October, 1981.     

Reaction of nitronium fluosulfate with fluoroolefins

Conclusions We were the first to add nitronium fluosulfate to the multiple bond of fluoroolefins to give the corresponding fluorinated -nitroalkyl fluosulfates. The theory was expressed that the electrophilic mechanism applies to the given process.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 6, pp. 1437–1441, June, 1983.     

Esterification of polyfluoroalkyl alcohols with tall oil rosin

Acid-catalyzed nonsolvent esterification of 1H,1H,5H-perfluoropentan-1-ol, 1H,1H,7H-perfluoroheptan-1-ol, and 1H,1H,9H-perfluorononan-1-ol with tall oil rosin was studied.     

Reaction of several resveratrol glycoside derivatives with hypochlorites in various media

The reactions of pterostilbenoside (trans-3,5-dimethoxystilben-4′-O-β-D-glucoside) and Ar–O–Tr derivatives of resveratroloside (3,5-dihydroxystilben-4′-O-β-D-glucoside) and pinostilbenoside (3-methoxy-5-hydroxystilben-4′-O-β-D-glucoside) with NaOCl and t-BuOCl in the presence of the stable nitroxyl radical TEMPO were studied in various media. It was found that the principal product of pterostilbenoside transformation was its 2,6-dichloroderivative, a part of which was oxidized to form 2,6-dichloropterostilbene glucuronide. Trityl ethers of resveratroloside and pinostilbenoside reacted with the hypochlorites to form mixtures of products.     

Reaction of alcohols and some nitrogen-containing compounds with 2-ethoxy-Δ3-dihydropyrans

The ethoxy group is replaced by the corresponding residue when 2-ethoxy-Δ³-dihydropyrans are heated with compounds having a labile hydrogen atom (alcohols, imidazoles, and urethanes). The stereochemical principles of the reaction of 6-substituted 2-ethoxy-Δ³-dihydropyrans with benzyl alcohol were studied.     

Reaction of chlorine with bromine

Different possible mechanisms for the gas phase reaction of formation of bromine chloride from bromine and chlorine are discussed. The rate of the reaction has been deduced from photometric measurements in conventional static reactors of surface-to-volume ratio ranging between 0.6 and 3 cm^?1, at temperatures between 51 and 113°C. Experimental data show that (1) the observed reaction is predominantly heterogeneous, and (2) the homogeneous reaction must proceed by an atomic chain mechanism initiated by Br atoms.     

Reaction of tertiary diacetylenic alcohols with amino alcohols

Conclusions It was shown that nitrogen-containing ethynyl vinyl ethers can be synthesized from tertiary diacetylenic alcohols and amino alcohols in the presence of alkaline catalysts.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 11, pp. 2604–2605, November, 1970.     

Reaction of fluorinated aldehydes with phenylacetylene

Conclusions Fluorinated aldehydes add to phenylacetylene with the formation of mixtures of ,-unsaturated fluoroketones and acetylenic fluoroalcohols.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 1, pp. 212–214, January, 1987.     

Generation of alkyl hypochlorites in oxidation of alcohols with carbon tetrachloride catalyzed by vanadium and manganese compounds

Primary alcohols and diols with various structures were subjected to transformations into esters, aldehydes, ketones, and lactones under the action of carbon tetrachloride in the presence of manganese compounds (MnCl₂, MnO₂, Mn(OAc)₂, Mn(acac)₃) and vanadium compounds (VCl₅, V₂O₅, VO(acac)₂) as catalysts. These transformation proceeded with the involvement of alkyl hypochlorites, which were generated in the course of oxidation of alcohols with carbon tetrachloride catalyzed by manganese or vanadium compounds. The optimum molar ratios between the catalyst and reagents were determined, and the reaction conditions for the highly selective synthesis of esters, aldehydes, ketones, and lactones from alcohols were found.     

Features of catalysis in the reaction of polyfluoroalkyl chlorosulfites with saturated monohydric alcohols

Synthetic opportunities and mechanism of catalysis of the reaction of polyfluororalkylchlorosulfites with saturated monohydric alcohols are considered. Kinetic measurements and quantum-chemical calculations showed that polyfluoroalkylation of these compounds proceeded through the step of complex formation involving reagents and catalyst followed by liberation of hydrogen chloride and sulfur dioxide and formation of polyfluoroalkyl ethers.
