1,2-Didehydroarenes (“arynes”) mediate as extremely reactive, short-lived intermediates in selective aryl–aryl coupling processes to form biaryls with unprecedented substituent patterns (see scheme, X=H, F, Cl). Possible applications include the synthesis of novel ligands for asymmetric catalysis.
Leroux et al. (2002) studied this question.
