Karboksyylihapoksi

Karboksyylihapoksi is a term used in Finnish chemistry to refer to compounds that combine a carboxyl group derived from a carboxylic acid with a peroxide functionality. In practice, the term is used descriptively and does not correspond to a single uniform structure. The concept encompasses classes such as carboxylic acid peresters (R-CO-O-O-R') and carboxylic acid hydroperoxides (R-CO-OOH).

Structure and naming: The most common structural motif is a carboxyl-derived fragment linked to a peroxide moiety. Because the term is not part of strict IUPAC nomenclature, its exact meaning may vary between sources. In many texts, karboksyylihapoksi serves as an umbrella for perester-type compounds and related peroxides that originate from carboxylic acids.

Applications and properties: These compounds are typically reactive and can act as oxidizers or radical initiators in organic synthesis and polymerization. They appear in some oxidation processes and in initiating polymerizations of vinyl monomers. Safety concerns are significant: peroxides and peresters can be unstable and sensitive to heat, impact, or friction, and may pose explosion hazards. Proper handling includes controlled storage, temperature management, and avoidance of incompatible materials.
