Deprotonation of the N-thiophosphorylated thioureas RC(S)NHP(S)(OiPr)2 (R = Me2N, HLI; iPrNH, HLII; 2,6-Me2C6H3NH, HLIII, 2,4,6-Me3C6H2NH, HLIV, aza-15-crown-5, HLV) and reaction with CuI or Cu(NO3)2 in aqueous EtOH leads to the polynuclear complexes [Cu4(LI-S,S’)4], [Cu8(LII-S,S’)8], and [Cu3(LIII-V-S,S’)3]. The structures of these compounds were studied by IR, 1H, 31P{1H} NMR, UV-visible spectroscopy and elemental analyses. The crystal structures of [Cu4L4I], [Cu8L8II], [Cu3LIII,IV3] were determined by single-crystal x-ray diffraction. Reaction of the deprotonated ligands (LI-V)– with a mixture of CuI and 1,10-phenanthroline (phen) or PPh3 leads to the mixed-ligand mononuclear complexes [Cu(phen)LI-V], [Cu(PPh3)LI-V] or [Cu(PPh3)2LI-V]. The same mixed-ligand complexes were obtained from the reaction of [Cu4L4I], [Cu8L8II], [Cu3LIII-V3] with phen or PPh3. In the experiment, the researchers used many compounds, for example, 1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3Reference of 66943-05-3).
1,4,7,10-Tetraoxa-13-azacyclopentadecane (cas: 66943-05-3) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides.Reference of 66943-05-3
