    Detection of atomic oxygen in flames by absorption spectroscopy (1994)
    Springer
    Applied physics 59 (1994), S. 543-546 
    Details
    ISSN: 1432-0649
    Keywords: 32.20 ; 42.55 ; 82.80

    Topics: Physics
    Notes: Abstract The absolute concentration of atomic oxygen in an atmospheric pressure hydrogen/air flame has been measured using Intracavity Laser Spectroscopy (ICLS) based on a dye laser pumped by an argon-ion laser. Absorptions at the highly forbidden transitions at 630.030 nm and 636.380 nm were observed at an equivalent optical length of up to 10 km. The relatively low intensity of the dye laser avoids photochemical interferences that are inherent to some other methods for detecting atomic oxygen. The detection sensitivity is about 6 × 1014 atom/cm3 and can be improved with better flame and laser stabilization.

    Synthesis of vinyl-substituted oxiranes and their transformation to dihydrofurans (1994)
    Springer
    Russian chemical bulletin 43 (1994), S. 1363-1367 
    Details
    ISSN: 1573-9171
    Keywords: 2-methylcyclohexanone ; aromatic and heterocyclic aldehydes ; Claisen—Schmidt reaction ; C-methylation ; Corey—Chaykovsky reaction ; spirooxiranes ; substituted hexahydroisobenzofurans

    Topics: Chemistry and Pharmacology
    Notes: Abstract The reaction of dimethylsulfonium methylide with the carbonyl function of 2-arylidene-cyclohexanones obtained from 2-methylcyclohexanone affords the corresponding spirooxiranes. The application of this reaction to 2,2-dimethyl-6-(5-methylfurfurylidene)cyclohexanone and 2,2-dimethyl-6-(5-chlorofurfurylidene)cyclohexanone leads to substituted 4,4-dimethyl-1-furyl-1,-3,4,5,6,7-hexahydroisobenzofurans.
