Routes to hydrido- and organo-iron complexes of the bidentate ligand o-phenylenebis(dimethylphosphine), o-C6H4(PMe2)2 (pdmp), have been developed, starting from trans-[FeCl2(pdmp)2]. Reduction of trans-[FeCl2(pdmp)2] with LiAlH4 gives the dihydride,

Publikováno v: Scopus-Elsevier

Treatment of [Cp2ZrCl2] with LiAlH4 and then [H3GaL] or of preformed [Cp2ZrH2] with [H3AlL] affords the heterobimetallic complexes [Cp2ZrH(μ-H)2AlH2(L)] (L = quinuclidine (1), NMe3 (2)). Density functional calculations gives an energy of association
