Abstract

Abstract Stoichiometric and catalytic hydrodefluorination reactions of fluorinated aromatic substrates on using [Rh (μ-H)(dippp)] 2 (1)(dippp= 1, 3-bis (diisopropylphosphino) propane) as catalyst and HSiEt 3 as a hydrogen source are reported. Treatment of the hydrido complex 1 with the fluoroarenes gave the fluorido complex [Rh (μ-F)(dippp)] 2 (2) and organic hydrodefluorination products. An unusual ortho-selectivity was observed in the ...
