The research focuses on the synthesis of monophosphine and diphosphine ligands for diplatinum polyynediyl complexes, with the aim of creating new functionality-containing systems and model compounds. The study involves a series of chemical reactions using various reactants, such as Br(CH2)4Br, NaO(CH2)2CH@CH2, KPPh2, CH3CH2OC(O)CH@C(CH3)2, and BrMg(CH2)3CH@CH2, among others. These reactants are subjected to different conditions and catalysts, like CuCl and Grubbs’ catalyst, to yield a variety of monophosphines and diphosphines. The synthesized compounds are then used to form platinum complexes, which are crucial for the study of 'insulated molecular wires'. The research also explores the introduction of Lewis basic functionality into the sp3 chains of the complexes. The experiments are confirmed through techniques like NMR spectroscopy, IR spectrometry, and mass spectrometry, which are used to characterize the new compounds and analyze their structures and purities. The study provides efficient syntheses of functionalized monophosphines and diphosphines, some of which are novel contributions to the field, with potential applications in areas such as fluorous chemistry and the formation of crown-ether-like metal complexes.
