Abstract

The synthesis and X-ray crystal structures of the following amidinate-substituted boron halides are reported: [^tBuC{N(Cy)} ₂]BCl(Ph) (1), [ⁿBuC{NCy}₂]BCl(Ph) (2), [(Me₃Si)₂NC{NCy}₂]BCl₂ (3) and [MeC{NⁱPr}₂]BCl₂ (4). Compounds 1, 2, and 3 were prepared via salt metathesis reactions of the appropriate lithium amidinates with PhBCl₂ or BCl₃. Compound 3 was also prepared by carbodiimide insertion into the B-N bond of (Me₃Si) ₂N-BCl₂. The latter method represents the first example of the insertion of a carbodiimide into a B-N moiety. The molecular structures of 1, 2, and 4 were determined by single-crystal X-ray diffraction.
