Abstract

Abstract The reactivity of [2] boraferrocenophane [(η 5-C 5 H 4)–BNMe 2–BNMe 2–(η 5-C 5 H 4) Fe](3) with borane and diborane compounds was examined, resulting in the complete loss of the–BNMe 2–BNMe 2–bridge and the concomitant formation of 1, 1′-borylated ferrocenes. With this unprecedented reactivity pattern, an alternative access to this class of compounds is established.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, ...
