N2 - The potassium graphite reduction of R-BBr3 (R- = :C{N(2,4,6-Me3C6H2)CH}2) in Et2O led to the isolation of 3 (R-(H)B=B(H)R-) and 4 (R-(H)2B-B(H)2R-), with B=B double and B-B single bonds, respectively. These compounds were characterized by single-crystal X-ray diffraction, 1H and 11B NMR, and elemental analyses. Neutral diborene 3 exhibits polymorphic planar (3a), twisted (3b), and trans-bent (3c) geometries in the solid state.
