Small-Ring Compounds. XXXIII. A Study by Nuclear Magnetic Resonance of the Extent of Isotope-position Rearrangement in the Vapor-phase Photochlorination of methyl-¹³C-Cyclopropane¹

Abstract

Vapor-phase photochlorination of methyl-^(13)C-cyclopropane was found to yield cyclopropylcarbinyl-α-^(13)C chloride and allyl-γ-^(13)C-carbinyl chloride. Within the experimental error of the analytical method (nuclear magnetic resonance spectroscopy), no other ^(13)C-position isomers of the chlorides were formed.
