Abstract
The invention relates to a process for preparing substituted polycyclo-alkylidene polycyclo-alkanes, such as substituted adamantylidene adamantanes, and the corresponding epidioxy compounds, in which polycyclo-alkylidene polycyclo-alkanes are halogenated with an N-halosuccinimide, tert.-butylhypohalite or sodium hypohalite/CH.sub.3 COOH, the halogenation product is optionally subjected to a substitution reaction, and the substituted polycycloalkylidene polycyclo-alkanes are converted to the corresponding epidioxy compounds in a way known per se. Further, the invention relates to compounds of formula 44 ##STR1## in which A and B represent alkylene radicals, which alkylene radicals may be attached to each other via an alkylene radical C, and R.sub.1 represents a substituent, which, in case of 4-eq.-R.sub.1 -2,2'-adamantylidene adamantane cannot be chloro, hydroxy, oxo, D or a group of formula 1: ##STR2## as well as to compounds of formula 45: ##STR3## in which A, B and C are as defined above, and R.sub.2 is a substituent which, in case of 4-eq.-R.sub.2 -2,2'-epidioxy-2,2'-adamantyl adamantane cannot be chloro or hydroxy. Compounds of formula 45 are useful as thermochemiluminescent la…
