Wd. Mcghee et al., SYNTHESIS AND STRUCTURE OF THE 1ST ETA(6)-PYRAZINE COMPLEX [V(ETA(6)-ME4PYRAZINE)(2)] AND RELATED STUDIES, Journal of organometallic chemistry, 459(1-2), 1993, pp. 125-130
The synthesis of vanadium and molybdenum complexes derived from nitrog
en-containing heterocyclic aromatic ligands are described. The first e
ta-pyrazine sandwich complex, [V(eta6-Me4pyrazine)2], has been prepare
d by metal vapour synthesis and crystallographically characterized. Th
e synthesis of (Mo(eta6-2,6-lutidine)2] has been substantially improve
d, and provides a convenient starting material for the preparation of
the new half-sandwich compounds [Mo(eta6-2,6-lutidine)(PMe3)3] and [Mo
(eta6-2,6-lutidine)(eta3-allyl)Cl]2.
