Abstract The 13 C NMR spectra of trans-and cis-fused bicyclo [4. n. 0] alkanes, where n= 4, 3 and 2, were determined. The distortion of the six membered ring, which is due to the strain arising from the 1, 2 fusion of cyclohexane with a smaller ring, is apparent mainly for the chemical shifts of the ring junction carbons. Both for the trans-and for the cis-fused hydrocarbons the results support a cyclohexane in a chair conformation, distorted to a ...
