Trifluoromethyl-substituted pyridyl- and pyrazolylboronic acids and esters: Synthesis and Suzuki-Miyaura cross-coupling reactions

Clapham, Kate M.,Batsanov, Andrei S.,Bryce, Martin R.,Tarbit, Brian

supporting information; experimental part, p. 2155 - 2161 (2009/09/04)

The synthesis of trifluoromethyl-substituted pyridylboronic acids and pyrazolylboronic esters is described via lithiation-boronation protocols (Schemes 1, 3 and 4). A study of their palladium-catalysed cross-couplings with heteroaryl halides is presented.
