Abstract
The reaction of SbBr3 with the complex metal carbonyl anions [π-C5H6(CO)3M]Na (M = Mo, W) leads to the formation of transition metal antimony bromides π-C5H5(CO)3M-Sb̅-Br2, which can be further metallated, yielding the stable species [XXX] All bromine substituted transition metal stibines prove to be excellent coordinating ligands and can easily be introduced into activated metal carbonyls. The interaction of π-C5H5(CO)3M-Sb̅Br2, with bromine results in a quantitative Sb-M bond cleavage, presumably via primary formation of pentavalent intermediates. All new compounds are fully characterized by means of IR, 1H NMR and mass spectroscopy.Keywords
