(a) Phenyl substituents are used to block the Ullmann coupling at the C–Br positions. Monoselective C–H bond activation and C–C dehydrogenative coupling can be obtained with DBMTP or DBOTP precursors. (b) The selectivity of the cross-coupling reaction between BB and EBB precursors can be efficiently steering by controlling the relative ratio and/or total coverage.
