Abstract

The syntheses and molecular structures of four compounds are reported: 1 (RBBr₃), 2 (R(H)₂B-B(H)₂R), 3 (R(H)B=B(H)R), and 4 (RBH₃) (R = :C{N(2,6-Prⁱ₂C₆H₃)CH}₂). These compounds were characterized by single-crystal X-ray diffraction, ¹H and ¹¹B NMR, and elemental analyses. Compounds 2 and 3 were prepared by the KC₈ reduction of 1 in Et₂O. Compound 3 is the first structurally characterized neutral diborene (mean B=B: 1.560(18) Å). The nature of the B=B double bond in 3 was delineated by DFT computations.
