Abstract: The site selectivity of 7-isopropylidene- and 7-( I-phenylethylidene)norbornadiene in 1,3-dipolar cycloadditions with C,N-diphenylnitrone, C-benzoyl-N-phenylnitrone, ethyl diazoacetate, azidoforrnate, ethylazidoacetate, 5-azido-2-furancarbaldehyde, p-nitrophenyl azide, tosyl azide, benzo- and benzoylnitrile oxide has been studied. The results are confronted with the site selectivity of 7-oxabicyclo[2,2,1]hepta-2,5-diene.
