Photochemical reaction of the olefin with hydrogen bromide gives as the major products a mixture of erythro- and threo-1-bromo-1,2,3,3,3-pentafluoropropane and 2-bromo-1,1,1,2,3-pentafluoropropane in the ratio 70 : 16. The threo-adduct undergoes dehydrobromination to give a mixture of...
Chloroacetaldehyde and formyl chloride also formed from the reaction of dichloropropylene with hydroxyl radicals (Tuazon et al., 1984). The evaporation half-life of cis-1,3-dichloropropylene (1 mg/L) from water at 25°C using a shallow-pitch propeller stirrer at 200 rpm at an average ...
and Xare each independently selected from the group consisting of fluorine, chlorine, bromine and iodine, to produce a reaction product comprising a compound of CFCH═CHX, wherein Xis as described above; and when Xis not fluorine, fluorinating the compound to produce 1,3,3,3-tetrafluoroprop...
Reaction of (5, X = H, Cl, Br) with methyl lithium in ether in the presence alkenes leads to cyclopropanes, e g.(6), apparently derived by trapping of an intermediate carbene (4); in the case of (5, X = Br), the precursor of the carbene, a cyclopropene (1, X=Y=Cl, Z=Me...
1-BROMO-2-METHYLPROPENE, with the chemical formula C4H7Br and CAS registry number 3017-69-4, is a compound known for its applications in various chemical processes. This colorless liquid, also referred to as 2-Methyl-1-bromopropene, is characterized by its bromine and methyl functional groups...
bromine and iodine it is selected to independence]; When (b) X formula (iii) is not fluorine, to fluorine converting the chemical compound formula (iii), formula (iii) [here, X is the above-mentioned sort, X fluorine is] produces the reaction product which includes chemical compound; Altho...
(where X =Cl or Br and a =1-4), mixtures formed by the reaction of antimony trifluoride with chlorine or bromine, or antimony pentafluoride. Such fluorinations are discussed by Hudlicky in Chemistry of Organic Fluorine Compounds, published by The MacMillan Company (New York), 1962, pages ...
(m+n) value of 0.005. With stirring, a mixture of 4.7 g allylamine and 7.1 g triethylamine was added to 200 g of the HFPO polymer and reaction was effected at 50 to 60° C. for about one hour. At the end of reaction, the formed salt was filtered off. To the solution were added...
Reaction of 1,2,3-triphenylcyclopropene with free bromine in solvents of variable polarityThe three-membered ring of 1,2,3-triphenylcyclopropene is retained during radical bromination and is opened during electrophilic bromination, in which connection the character of the solvent......
In order to investigate the reactivity of naphtho[b]cyclopropene ( 2 ), the reaction with various dienophiles, dienes and electrophiles was examined. Reaction of 2 with tetracyanoethylene, 4-phenyl-3H-1.2,4-triazole-3,5(4H)-dione, 1,3-diphenylisobenzofuran and benzyne afforded the ...
