| Abstract: | The abnormally bound, anionic NHC–borane complex [Ru(IDipp‐BF3)(p‐cymene)Cl]2 ( 4 ; IDipp‐BF3=1,3‐(2,6‐iPr2C6H3)2‐2‐BF3(C3HN2)‐4‐yl) was synthesized by transmetalation from Li[(IDipp‐BF3)2Ag]. Addition of donors gave species of the form [Ru(IDipp‐BF3)(p‐cymene)(L)Cl], whereas halide abstraction with Ag(Et2O)[B(C6F5)4] gave C?H activation of the methine position of the IDipp?BF3 ligand. |
