Abstract
The action of two equivalents of 1,2-bis(diphenylphosphino)-4-tert-butylcyc lopentadienyllithium on FeCl2 led to the corresponding 1,1',2,2'-tetraphosp hinoferrocene. The X-ray structure of this bulky ferrocene is described. Th e spectroscopic results reveal a conformational chirality with a cisoid dis position of the phosphino groups. The first results about the complexation with representative elements of Group IX and X (Rh, Pd, Ir) are reported. ( C) 2001 Elsevier Science B.V. All rights reserved.
