Template-controlled synthesis of a planar [16]ane-P2C(NHC)2 macrocycle.
نویسندگان
چکیده
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]ane-P(2)C(NHC)(2) ligand.

Template 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 کاملA macrocyclic silver polycarbene complex based on 1,2,4-triazole units: synthesis and postsynthetic modification.
Facile synthesis and postsynthetic modification of a rectangular 1,2,4-triazole-based NHC macrocycle have been developed. The silver complex [Ag2(1)2](BF4)2 is derived from the corresponding triazole salt H2-1(BF4)2 upon reaction with Ag2O. The structure of the metallocyclic Ag-NHC complex [Ag2(1)2](BF4)2 was determined by single-crystal X-ray diffraction analysis. The metal-carbene template un...
