摘要：

The first examples of Pb-containing cyclic polysulfides, 1,2,3,4,5-tetrathiaplumbolanes (R(1)R(2)-PbS4: 2 (R(1) = Tbt, R(2) = Tip), 3 (R(1) = Tbt, R(2) = Ttm), and 4 (R(1) = R(2) = Tip); Tb t = 2,4,6-tris[bis(trimethylsilyl)methyl]phenyl, Tip = 2,4,6-triisopropylphenyl, and Ttm = 2,4,6-tris[(trimethylsilyl)methyl]phenyl), were synthesized and isolated as stable crystalline compounds by sulfurization of the corresponding kinetically stabilized diarylplumbylenes Tbt(Tip)Pb: (6), Tbt(Ttm)Pb: (7), and Tip(2)Pb: (10). The molecular structures of the novel lead-containing metallacycles 2 and 4 were determined by X-ray crystallographic analysis.
