✦ Synopsis

VariabZe temperature 'h' nmr spectrometry has shown that the Tmstable" isomer of monoclehydroC14lanmlene possesses the symmetrical di-trans configuration I or 2, and the %tubZe" isomer (the precursor of C14lannulenel possesses the tri-e configuration 2.

15.2 Hz, J5 4 = J12 l3 12.0 Hz, H-5, H-12). In the previously reported 385 spectrum of 2 at 27O the broad ba;d at cu. 6 0.5 had been neglected.
