[2-(CH3ECH2)C6H4]PbPh3−nCln (n = 0, E = O （4), E = S(5)）的合成n = 1, E = 0 (6), E = S (7)；n = 2, E = 0(8)。核磁共振和单晶数据表明，随着n从0到2的增加，显著的Pb⋯E相互作用增加。Pb⋯E相互作用稳定了Pb -芳基键，以至于4和5与Me2SnCl2的反应导致Ph基团和Cl的交换，分别产生6和7，以及Me2PhSnCl。
The syntheses of [2-(CH3ECH2)C6H4]PbPh3−nCln, (n = 0, E = O (4), E = S (5); n = 1, E = O (6), E = S (7); n = 2, E = O (8), are described. NMR and single crystal data illustrate significant Pb⋯E interactions increasing as n progresses from 0 to 2. The Pb⋯E interactions stabilize the Pb–aryl bonding to the extent that the reactions of 4 and 5 with Me2SnCl2 result in interchange of a Ph group and Cl to produce 6 and 7, respectively, together with Me2PhSnCl.
