Me 2 Si(C 5 Me 4) 2 Cr : synthesis and crystal structure of a ligand-free ansa-chromocene

Type of Publication: Journal article
Author: Schaper, Frank; Wrobel, Olaf; Schwörer, Ralf; Brintzinger, Hans-Herbert
Year of publication: 2004
Published in: Organometallics ; 23 (2004), 14. - pp. 3552-3555. - ISSN 0276-7333. - eISSN 1520-6041
DOI (citable link): https://dx.doi.org/10.1021/om049901x
Summary:
Me2Si(C5Me4)2Cr, the first example of an ansa-chromocene containing no additional ligands at chromium, was synthesized from Me2Si(C5Me4)2Li2 and CrCl2(THF)x in the presence of 2,6-xylyl isocyanide. The crystal structure of the complex was determined. The complex is paramagnetic and does not coordinate phosphines, phosphites, nitriles, amines, or acetylenes, but it reacts readily with 2,6-xylyl isocyanide to give mono- and diisocyanide complexes.
