INFRARED AND RAMAN SPECTROSCOPIC STUDIES ON MOLECULAR CONFORMATIONS OF F(CH2)nF (n=3-6)

The infrared and Raman spectra of F(CH2)nF (n=3-6) were measured and analyzed on the basis of the normal coordinate treatment.The spectral analyses indicated that the molecule in the solid state takes the gauche-gauche conformation for n=3, gauche-trans-gauche' for n=4, gauche-trans-trans-gauche for n=5, and gauche-trans-trans-trans-gauche' for n=6.

Reaction of diethylaminosulfur trifluoride with diols

Diethylaminosulfur trifluoride (DAST) reacts with dialcohols to give difluorides, sulfite esters or cyclic ethers depending on the number of carbons separating the two alcohol groups.Vicinal and 1,3-diols give large amounts of sulfite ester products while butane-1,4-diol gives almost exclusively the cyclic ether tetrahydrofuran.Terminal dialcohols longer than four carbons give primarily difluoride products.Semiempirical calculations indicate a preference for cyclic intermediates when four or less carbons separate the two alcohol moieties.These cyclic intermediates lead directly to the cyclic ethers and sulfite ester products.

The Preparation of Primary Alkyl and Benzyl Fluorides from the Corresponding Primary Amines

N-substituted 2,4,6-triphenylpyridinium fluorides (in contrast to these and other tetrafluoroborates) thermolyse to the corresponding primary alkyl and benzyl fluorides.The pyridinium fluorides are made from 2,4,6-triphenylpyrylium fluoride and the relevant amine.

Reaction of OH with CH3CH2F. The Extent of H Abstraction from the α and β Positions

The mechanism of the reaction of OH radicals with C2H5F was determined from the yields of the reaction products.Hydroxyl radicals were generated in the gas phase by photolysis of H2O at 184.9 nm, and products were analyzed by gas chromathography and mass spectrometry.The reaction proceeds by abstraction of hydrogen primarily from the α position, and the major products were meso- and d,l-2,3-C4H8F2, 1,3-C4H8F2, 2-C4H9F, and H2.The minor products were 1,4-C4H8F2, 1-C4H9F, 1-and 2-C3H7F, C2H6, C2H4, C2H3F, and C2H2.It was found that kinetically hot H atoms formed in the photolysis of H2O abstract hydrogen to some extent at the β position of C2H5F in contrast to thermal H atoms which abstract exclusively at the α position.After correction for the effects of H atom reactions, it was estimated that 85+/-3percent of the abstraction by occurs at the α position of C2H5F.
