Organotransition-Metal Metallacarboranes. 16.(1) Directed Synthesis of Arene-Linked Metal Sandwich Complexes via Controlled Substitution on Boron

摘要

The carborane ligands nido-2,3-R2C2B4H42- and cyclo-R2C2B3H34-form monomeric andoligomeric metal sandwich complexes of unusual stability and structural novelty. Although these groups are steric and isoelectronic surrogates for arenes or cyclopentadienide (C5R5), they are much more versatile organometallic building
