Palladium, platinum and rhodium 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(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)2PdCl2 but poorer than (dppf)PdCl2 in diethyl ether.
Graphical abstractRac and meso isomers of bis(1-diphenylphosphinoindenyl)iron(II) (1) were used to prepare four-coordinate Pd, Pt and Rh complexes. Some cross-coupling catalytic studies of the PdCl2 complex of rac-1 are described along with the structures of both rac and meso isomers of 2.Figure optionsDownload full-size imageDownload as PowerPoint slide
