摘要：

The cyclopentadienylboranes I-XI have been synthesized by the reaction of halogenoboranes with cyclopentadienyl-trimethylsilanes, -trimethylstannanes and -lithium compounds. Substitution reactions at the boron atom in III and VIII with tetramethylstannane and dimethylamine lead to the cyclopentadienylboranes XII-XV. The structures of I-XV have been investigated by 1H-, 13C- and 11B-n.m.r. measurements. The 5-trimethylsilyl-cyclopentadienylboranes show a dynamic behaviour due to sigmatropic rearrangements. The influence of a boryl ligand on the speed of these rearrangements is discussed. © 1979.
