A fast, convenient and ligand-free protocol for the synthesis of a series of 4-aryl-substituted triphenylamine derivatives by a palladium-catalysed aerobic Suzuki reaction of aryl halides with [4-(diphenylamino)phenyl]boronic acid in aqueous iPrOH is described. Importantly, both aryl bromides and heteroaryl halides afforded good to excellent yields under mild conditions.
There is disclosed a compound which is an N-heterocycle having at least one substituent of Formula (I), In Formula I: Q1, Q2, Q3, Q4, and Q5 are the same or different and can be N or CR1; R1 is the same or different at each occurrence and can be H, D, CN, hydrocarbon aryl, heteroaryl, deuterated hydrocarbon aryl, or deuterated heteroaryl; and * represents a point of attachment to N in the N-heterocycle. In Formula I, at least one of Q1 through Q5 is N and at least one of Q1 through Q5 is C-CN.
