Ruthenium complexes of κ(P)-and κ(P)-η 6 - coordinated KITPHOS monophosphines: Efficient catalysts for the direct ortho arylation of 2-phenylpyridine and N-phenylpyrazole with aryl chlorides

Academic Article

Abstract

  • Thermolysis of the P-coordinated KITPHOS monophosphine complex [(p-cymene)RuCl 2 (KITPHOS)] in chlorobenzene at 120 °C resulted in displacement of the p-cymene to afford [{κ(P)-η 6 -KITPHOS} RuCl 2 ], the first example of a constrainedgeometry complex in which the κ(P)-bonded diphenylphosphino group and the η 6 - coordinated proximal phenyl ring are connected by an unsaturated two-carbon tether; both complexes form efficient catalysts for the direct ortho arylation of 2-phenylpyridine and N-phenylpyrazole with a range of aryl chlorides. © 2011 American Chemical Society.
