Reaction of i-heptafluoropropyl radicals with cyanogen chloride

Abstract

The gas-phase reaction of i-C,F, radicals with cyanogen chloride has been studied between The main product, 2-~hloroheptafluoropropane, is formed via chlorine-atom abstraction by (6) 70 and 330 OC, using heptafluoro-2-iodopropane as the free-radical source.i-C,F, :for which log,, [(k,/kk)/cm: mol-4 s-k] = 6.27-14.41/2.303 RT was obtained. At lower temperatures the Arrhenius plot shows curvature. This was interpreted as the occurrence of another reaction producing C,F,Cl, which could be

Probing halogen bonding interactions between heptafluoro-2-iodopropane and three azabenzenes with Raman spectroscopy and density functional theory

“…1), a halogen rich molecule with uses in organometallic synthesis. [8][9][10][11][12][13][14][15] The electron withdrawing fluorinated carbon atoms adjacent to the donor atom, iodine in this case, strengthen its s-hole which potentially results in stronger halogen bond formation. This molecule is analysed spectroscopically in solution and with computational chemistry when interacting with three potential halogen bond acceptors: pyridine, pyrimidine, and pyridazine.…”

A novel and efficient synthetic route to perfluoroisobutyronitrile from perfluoroisobutyryl acid

“…[1][2][3] On-going research in General Electric (GE), America has led to the emergence of some new insulating gases like CF 3 I, c-C 4 F 8 , i-C 5 F 10 O, and i-C 4 F 7 N. There are handful reports about the synthesis of i-C 4 F 7 N, furthermore most of them aren't practical to apply in industry. [4][5][6][7][8][9][10][11] The gas i-C 4 F 7 N, when mixed with CO 2 , exhibits excellent properties, which surely be one of the rst choices to replace SF 6 . Besides, the GWP of i-C 4 F 7 N is only 2210, which is far lower than that of SF 6 .…”

The gas-phase reaction of CF3radicals with HCN in the temperature range 333–523 K

“…Similar behaviour was observed for the reactions of C2F5, n-C3F7 and i-C3F7 with C1CN. [5][6][7] We now present results for the reaction of CF3 radicals generated by photolysis of CF,I with HCN in the temperature range 333-523 K.…”
