Three-foot capping ligand, synthesis method thereof, molybdenum-containing complex with the three-foot capping ligand, and synthesis method thereof

The invention provides a novel three-foot capping ligand, a synthesis method thereof, a molybdenum-containing complex with the three-foot capping ligand, and a synthesis method thereof. The three-foot capping ligand (L) is a nitrogen-containing hetero-cyclic compound. Because the ligands on the complex are easy to replace and modify, so that when properties of a cluster compound is not satisfied, the ligand, or substituent groups thereof, can be targetly modified; meanwhile, with a tricyanogen construction module, multinuclear cluster compounds in different structure types can be conveniently and controllably synthesized.

Catalytic activity of 1-methylimidazole-based phosphine ligands in the palladium-catalyzed Suzuki coupling reaction

The catalytic activities of three N-methylimidazole-based phosphine ligands in the Suzuki coupling reaction were tested using PdCl2 as the catalyst. The results showed all three phosphine ligands exhibited excellent activity towards the Suzuki reaction, and the catalytic activity decreased with increasing number of imidazole groups.

Synthesis and Coordinating Properties of Heterocyclic-Substituted Tertiary Phosphines

Tris(thiazol-2-yl)phosphine, 2,has been prepared by the reaction of corresponding heteroaryl organolithium reagent and PCl3.Attempts to prepare other heteroaryl-substituted phosphines, such as tris(benzothiazol-2-yl)-(3) and tris(1-methylimidazol-2-yl)phosphines (6), using this procedure, were unsuccessful.Heteroaryltrimethylsilanes, readily accessible from the reaction between a heteroaryl organometallic reagent and chlorotrimethylsilane (CH3SiCl), afford the desired heteroaryl-substituted phosphines when treated with PCl3.The heteroaryl-silicon bonds of this silanes also undergo facile electrophilic cleavage by (C6H5)PCl2 and (C6H5)2 PCl and yield the unsymmetrically substituted phosphines.The phosphines obtained in this work react readity with (1,5-cyclooctadiene)dimethylplatinum(II) and generate cis-dimethylbis(phosphine)platinum(II) complexes in which the potentially multidenate ligands are exclusively monodentate.The coordinated phosphines are bound to platinum through the phosphorus atom of the ligand.
