Four-coordinate complexes of bis(1-diphenylphosphinoindenyl)iron(II)
摘要:
Palladium, platinum and rhodiurn complexes of rac- and meso-bis(1-diphenylphosphinoindenyl)iron(II) (1) are reported. Both rac and meso isomers of {bis(1-diphenylphosphinoindenyl)iron(II)} palladium dichloride (rac- and meso-2) were characterized by X-ray crystallography along with the rac isomer of the Pt analogue (rac-3). NMR analysis of the rhodium complex [{bis(1-diphenylphosphinoindenyl)iron(II))(cyclooctadiene)rhodium(l)I tetraphenylborate suggests a similar structure in solution. Coupling reactions of n- and sec-BuCl with bromobenzene in THF are catalysed by rac-2 and found to be similar to (PPh3)(2)PdCl2 but poorer than (dppf)PdCl2 in diethyl ether. (c) 2006 Elsevier B.V.
