    • The rather significant dissimilarity in the chemical shifts of the hydrogens of the cyclopropyl function is due to long-range shielding by the urazole ring. A molecular model of 12 indicates that one of the methylenes of the cyclopropyl function resides almost in the plane of the urazole ring and suffers extensive deshielding. Similar deshielding effects have been observed in the alkenylidenecyclopropane-2 adducts (1,6).
