Pyridine promotes dediazoniation of aryldiazonium tetrafluoroborates. The formed aryl radicals were trapped with B2pin2, iodine, or tetrahydrofuran to afford boronic esters, iodobenzenes and benzenes, respectively. The application to the synthesis of (pentafluorosulfanyl) phenylboronic esters, iodo(pentafluorosulfanyl)benzenes and (pentafluorosulfanyl)benzene is shown.

Paragraph 0115-0116, (2019/03/30)
Novel silicon containing compounds for organic electroluminescent devices is disclosed. The compounds can be used as emitters in the emissive layer of the organic electroluminescent device. More specifically, these compounds can emit blue light. The devices incorporating these compounds as emitters show unexpecting higher efficiency and longer lifetime than prior art compounds. Also disclosed is an organic electroluminescent device and a formulation.
Use of 2-bromophenylboronic esters as benzyne precursors in the Pd-catalyzed synthesis of triphenylenes
Garcia-Lopez, Jose-Antonio,Greaney, Michael F.
, p. 2338 - 2341 (2014/05/20)
ortho-Substituted aryl boronates are introduced as aryne precursors for transition-metal-catalyzed transformations. On treatment with tBuOK and Pd(0), metal-bound aryne intermediates are formed that undergo effective trimerization to form useful triphenylene compounds. For meta-substituted arynes, the 3:1 product ratio in favor of non-C3 symmetric material is indicative of a benzyne mechanism.
