Synthesis of 3,3-diisopropyl-4-methoxy-4-(siloxy-2-naphthyl)-1,2-dioxetanes and their F −-induced chemiluminescent decomposition

Abstract

Six isomeric 3,3-diisopropyl-4-methoxy-4-(siloxy-2-naphthyl)-1,2-dioxetanes ( 3) were synthesized and their F −-induced chemiluminescencent 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.
