Abstract

1,3,4,5-Tetraethyl-2-methyl-1,3-diborolene (5) reacts with nickelocene and dimeric cyclopentadienylcarbonylnickel, yielding orange red 4 a, a diamagnetic nickelocene analogue. 1H and 11B NMR data indicate a sandwich structure, which is confirmed by X-ray structure analysis. The title compound crystallizes in the space group Pnma with a = 9.265(I), b = 15.1343(9), c = 12.777(2) Å and four molecules in the unit cell. All metal carbon distances are similar to those of the isoelectronic ferrocene.
