- W13463501 abstract "Group 14 metal(II) alkyl complexes are very rare, with few examples being studied ingreat detail. To this end, a series of β-diketiminate lead(II) alkyl and aryl complexes,[{(2,6-iPr2C6H3)NC(CH3)}2CH]PbR (R = Me, iPr, sBu, Np, Bn, tBu and Ph) weresynthesised and a number of computational studies were performed on them to increasethe understanding of the nature of these compounds. Reactivity studies on both the lead,and the analogous tin systems, showed that they could be used as precursors to generateexamples of very rare two-coordinate group 14 metal cation complexes, including thefirst example of a β-diketiminate two-coordinate lead(II) cation, and an analogousexample of a rare low-coordinate tin(II) system. These were studied in detail bycomputational methods, including the stabilising effects of a coordinated solventmolecule on the metal centre.β-Diketiminate magnesium alkyl complexes were generated to investigate the +2oxidation state metal environment without the presence of a stereochemically activelone pair, as present in the group 14 metal(II) complexes. A carbodiimide wassuccessfully inserted into the magnesium-carbon bond, and novel magnesiumphosphides were generated from the alkyl complexes. Solvent stabilisation effects onthese phosphides were also studied by computational methods.A series of macrocyclic amines and amine ethers were synthesised to investigate thehydrolysis of a phosphate diester model RNA system by lead(II) salts, monitored byUV-visible kinetics. The reaction kinetics gave no reproducible results, but thesyntheses of the macrocycles are presented in detail for further citation." @default.
