Tris(trimethylsilyl)methyl-lead Oxinates: Their Solvolysis, Redistribution, and Reductive Elimination Reactions

The complex PbMe2(ox) (where ox = the anion of 8-hydroxyquinoline) is stable to boiling ethanol over short periods, but on prolonged heating undergoes redistribution and reductive elimination reactions yielding Pb(ox)2, PbMe3(ox), PbMe3, and 8-methoxyquinoline.By contrast, when PbCl2Me is treated with 8-hydroxyquinoline at pH ca. 10 in methanol, ethanol, or aqueous dioxan the bis(trimethylsilyl)methyl complex PbMe(ox)2 (1) is formed together with SiMe3(OR) (R = H, Me, or Et) rather than the expected tris(trimethylsilyl)methyl complex.Refluxing (1) in ethanol or aqueous dioxan results in further nucleophilic displacement of SiMe3 groups yielding , successively, PbMe(CH2SiMe3)(ox)2 (2) and PbMe2(ox)2 (3).These cleavage reactions occur in competition with disproportionation and reductive elimination processes, the final products derived from (3) being Pb(ox)2, PbMe4, PbMe3(ox), and 8-methoxyquinoline.The corresponding 8-hydroxy-2-methylquinolinate complexes are also examined.
