摘要：

Time to B radical: One-electron reduction of 1-ferrocenyl-2,3,4,5- tetraphenylborole results in a radical anion with 5 π electrons in the borole ring. Both EPR spectroscopic investigations and spin density calculations confirm the formation of a borol radical (see picture). Further reduction stimulates an intramolecular [(C5H5)Fe] migration from the cyclopentadienyl anion to the borole dianion. © 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
