✦ Synopsis

The synthesis of the protected phenolate-substituted 1,2-dioxetanes I and 2, containing the substituent directly linked to the peroxidic ring or separated by a methylene group, is reported. The activation parameters and chemiluminescence quantum yield~ upon unimolecular and catalyzed decomposition of I and 2 are m agreement with the occurrence of an intramolecular CIEEL mechanism in the catalyzed decomposition ofth~e dioxetanes.
