Bischalcogenides and transition metal complexes of cyclodiphosphazane derived diphosphaferrocenophane
摘要:
Oxidation reactions and transition metal chemistry of diphosphaferrocenophane [Fe(eta(5)-C5H4)(2)(mu-(PNBu)-Bu-t)(2)] (1) has been reported. The reactions of 1 with aq. H2O2 and elemental selenium afforded bis-chalcogenides, [Fe(eta(5)-C5H4)(2)(mu-P(E)(NBu)-Bu-t)(2)] (E = O; 2, E = Se; 3). Treatment of 1 with [Rh(COD)Cl](2) and [Pd(eta(3)-C3H5)Cl](2) in 1:1 molar ratio afforded binuclear complexes, [(RhCl(COD))(2)(Fe(eta(5)-C5H4)(2)(mu-(PNBu)-Bu-t)(2))] (4) and [[Pd(eta(3)-C3H5)Cl}(2)Fe(eta(5)-C5H4)(2)(mu-(PNBu)-Bu-t)(2)}] (5), respectively. The mixed-ligand binuclear Cu-I complex [{(2,2'-bpy)CuI)(2){Fe(eta(5)-C5H4)(2)(mu-(PNBu)-Bu-t)(2)}] (6) was synthesized by the reaction of 1 with Cul followed by treatment with 2,2'-bipyridine. The reaction between 1 and [AuCl(SMe2)] in 1:2 molar ratio yielded the dinuclear complex [(AuCl)(2){Fe(eta(5)-C5H4)(2)(mu-(PNBu)-Bu-t)(2)}] (7) showing intermolecular aurophilic interactions in the crystal lattice. The crystal structures of 2, 4-7 were established by single-crystal X-ray diffraction studies. (C) 2015 Elsevier Ltd. All rights reserved.
Synthesis and Molecular Structure of 1,3-Di-tert-butyl-2,4-bis(cyclodipentadienyl)iron(II) 1,3,2,4-Diazadiphosphetidine, [Fe(η5-C5H4)2(PNtBu)2]
摘要:
The reaction of the dichlorocyclodiphosphazane (also called dichlorodiazadiphosphetidine), [ClP(mu-(NBu)-Bu-t)](2), with in situ generated ferrocene dilithiate in a 1:1 molar ratio affords the first metallocene derivative of a diazadiphosphetidine, 1,3-di-tert-butyl-2,4-bis(cyclopentadienyl)iron(II) 1,3,2,4-diazadiphosphetidine, [Fe(eta(5)-C5H4)(2)((PNBu)-Bu-t)(2)], in good yield.

Two novel zeolitic phosphane cluster frameworks have been synthesized by using ferrocenyl cyclodiphosphazanes [Fe(η5-C5H4)2P(μ-NtBu)}2] as ditopic linkers and [Cu4X4] clusters as tetrahedral nodes.
GRAPHICAL ABSTRACT ABSTRACT The reactivity of cyclodiphosphazanes towards various transition metal derivatives has been studied. The products obtained showed simple monomeric to di-, tetra-, or pentameric structures. The interactions between cyclodiphosphazanes and copper halides resulted in the formation of several one-dimensional (1D), 2D, or 3D coordination polymers having adamantanoid, diamondoid
