Abstract

Abstract Monosubstituted cyclohexanes were synthesized by addition of a cyclohexyl radical to olefins bearing different substituents at the α-position. Six distinct methylene 13 C resonances were observed, indicating that the methylene carbons located at the 2 and 6 positions and at the 3 and 5 positions are not magnetically equivalent. This magnetic non- equivalence (anisochronism) observed in the monosubstituted cyclohexanes is due to the ...
