Six isomeric 3,3-diisopropyl-4-methoxy-4-(siloxy-2-naphthyl)-1,2- dioxetanes (3) were synthesized and their F^--induced chemiluminescent decomposition were examined in DMSO. The 'odd/even' relationship in Φ(CL) holds for all the dioxetanes (3). On the other hand, the 'odd/even' relationship in emission half-lives t(1/2) is observed for dioxetanes (3c- 3f) with a trigger on the ring B but not for dioxetanes (3a and 3b) with a trigger on the ring A.
