General description
1,2-Diethylbenzene can be used as a reactant in the preparation of pseudocyclic diaryliodonium triflates, 5,6-disubstituted indanone intermediates via intramolecular Friedel-Crafts alkylation, dibromide intermediates via radical bromination, and in the dehydrogenative C-H/C-H arylation of indolines.
Application
- Attraction of adult Harmonia axyridis to volatiles of the insectary plant Cnidium monnieri: This study investigates the attraction of the beetle Harmonia axyridis to 1,2-diethylbenzene, indicating potential uses in biological control strategies (Zhiping et al., 2020).

Following a lipophilicity-based hypothesis, an 8-hydroxyquinolinone 2-aminoindan derived series of beta(2)-adrenoceptor agonists have been prepared and evaluated for their potential as inhaled ultralong-acting bronchodilators. Determination of their activities at the human beta(2)-adrenoceptor receptor showed symmetrical substitution of the 2-aminoindan moiety
