Synthesis and reactivity of NHC-based rhodium macrocycles.
Using a general synthetic procedure employing readily accessed terminal alkene-functionalized pro-ligands and macrocyclization by ring-closing olefin metathesis, rhodium carbonyl complexes have been prepared that contain lutidine (1a; n = 1) and pyridine (1b; n = 0) derived tridentate CNC macrocycles with dodecamethylene spacers. In solution, 1a shows temperature-invariant time-averaged C2 symm...
متن کاملTemplate controlled synthesis of a coordinated [11]ane-P2C NHC macrocycle.
Rhenium complex []Cl with the coordinated [11]ane-P(2)C(NHC) macrocycle was obtained by a metal template controlled ring formation reaction; in this reaction a coordinated NH,NH-stabilised imidazolidin-2-ylidene ligand was connected via the nitrogen atoms to two phenyl substituents of a 2-fluorophenyl substituted diphosphine ligand.
متن کاملTemplate-controlled synthesis of a planar [16]ane-P2C(NHC)2 macrocycle.
Reaction of tetraphosphine platinum(II) complexes with 2-azidoethyl isocyanide 3 in methanol leads to complexes with two trans-coordinated NH,NH-stabilized carbene ligands 6(X)(2). Complexes 6(X)(2) react with phenyldivinylphosphine under substitution of the remaining phosphine ligands followed by an intramolecular hydroamination reaction to produce complex 1(PF(6))(2) with a macrocyclic [16]an...
متن کاملCo-linear, double-uranyl coordination by an expanded Schiff-base polypyrrole macrocycle.
Expansion of a Schiff-base polypyrrolic macrocycle allows the formation of a binuclear uranyl complex with co-linear uranyl ions and a very short oxo-oxo distance.
متن کاملSelf-assembled metallo-macrocycle based coordination polymers with unsymmetrical amide ligands.
A series of metallo-macrocyclic based coordination polymers has been prepared from flexible amide ligands N-6-[(3-pyridylmethylamino)carbonyl]-pyridine-2-carboxylic acid (L1-CH(3)) and N-6-[(4-pyridylmethylamino)carbonyl]-pyridine-2-carboxylic acid (L2-CH(3)). In all but one case, self-assembled dinuclear metallo-macrocyclic units form the basis of the polymeric structures, whereby discrete met...
