The present application relates to a compound of a formula (I) which comprises a benzene group that is substituted with a group selected from carbazole derivatives and bridged amines and with an electron attracting group, wherein the two groups are located in the ortho-position in relation to one another. The present application further relates to the use of the compound of the formula (I) in an electronic device, and to a method of producing the compound of the formula (I).

The scope and limitations of direct arylation of fluorinatedaromatics with aryl sulfonates was examined. Pd(OAc)2, in the presence of MePhos and KOAc in THF, efficiently catalyzed the direct arylation of fluoro aromatics with aryl triflates under ambient conditions. Sterically hindered triflates and heteroaryl triflates gave good to excellent yields of the cross coupled products using a modified catalyst
