## Abstract The throughβring conjugation between Οβdonor and attractor substitutents on vicinal carbons of cyclopropane with the direct participation of the ring was assessed using proton and ^13^C NMR. Appropriate ^1^H NMR correlations were obtained between Οp and Ξ΄H of the trimethylene protons. H
IN 1953, Birch and Lahey' suggested for aromadendrene two alternative structures I and II with the cyclopropane ring in different pceitione, Ae aromadendrene on dehydrogenation affords S-guajazulene only, Birch et al, in their recent paper,2 prefer formula I. In view of the speculative character of
