Description

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).
