The 13C chemical shifts of cis-and trans-benzylidenepropylamine and substituted benzylideneanilines were analysed after additons of Eu(fod),. The cisltrans ratio increases as the amount of lanthanide shift reagent increased. The cis isomers showed large lanthanide-induced shifts, whereas the trans i
