Abstract
A large number of iron and ruthenium dinuclear complexes containing heteroatom substituted carbene ligands have been obtained by two different synthetic routes. The first method consists in reacting heteroatom substituted μ-carbyne cationic complexes with CN- ion. The second involves the displacement of the SMe2 molecule in the sulfonium [Fe2{μ-C(CN)(SMe2)}(μ-CO)(CO)2CP2]SO3CF3 by appropriate nucleophiles X- (X=OR, SR, NR2, PR2). Spectroscopic (IR, NMR) and structural investigations together with reactivity studies on these complexes have greatly contributed to better understanding the factors which favor bridging vs. terminal coordination of heteroatom substituted carbene ligands. © 1993 Plenum Publishing Corporation.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
