Wang, Xisheng published the artcilePd(II)-catalyzed para-selective C-H arylation of monosubstituted arenes, Formula: C6H5F4NO3S, the publication is Journal of the American Chemical Society (2011), 133(35), 13864-13867, database is CAplus and MEDLINE.
Pd-catalyzed highly para-selective C-H arylation of monosubstituted arenes (including toluene) is developed for the first time using an F+ reagent as a bystanding oxidant. This finding provides a new retrosynthetic disconnection for para-substituted biaryl synthesis e. g., I via C-H/C-H cross-coupling.
