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).

The bio-distribution of the neurotoxic 1,2-diethylbenzene (1,2-DEB) was studied in male Sprague-Dawley rats after intravenous administration of [(14)C] 1,2-DEB (1 mg kg(-1)). The highest concentrations of [(14)C] non-volatile metabolites, determined by whole-body auto-radiography, were in the nasal cavity, ethmoid turbinates

1. Biotransformation of 1,2-diethenylbenzene (1) in rat was studied. Five urinary metabolites were isolated by extraction of acid hydrolysed urine and identified by nmr and mass spectroscopy, namely, 1-(2-ethenylphenyl)ethane-1,2-diol (2) 2-ethenylmandelic acid (3), 2-ethenylphenylglyoxylic acid (4), 2-ethenylphenylacetylglycine (5) N-acetyl-S-[1-(2-ethenylphenyl)-2-hydroxyethyl]cysteine (6)
